travel limits on liquids

Calling All Travelers: These Are the Official TSA Liquid Rules

You don't want security to throw away your new, full-size bottle of shampoo do you?

Every item on this page was chosen by a Town & Country editor. We may earn commission on some of the items you choose to buy.

We're in the midst of peak travel season, folks. Kids are still on summer break and the working world is finally using their vacation time to soak up the late summer rays before fall settles in. If you're hopping on a plane soon and traveling with only a carry-on (we salute you), there are some TSA liquid rules you should know about.

We've all fallen victim to TSA while traveling; here's a refresher so you don't make the same mistakes again.

TSA Liquid Rules:

According to the TSA website , these rules apply for liquids, aerosols, gels, creams, and pastes.

All liquids must be in a 3.4oz or smaller container. Your serums, creams, cleansers, and masks are too expensive to lose, so check their sizes and if they're too big, leave them at home or transfer them to a smaller container.

They have to be able to fit in a quart-size bag. Before you throw 10 containers of liquids into your carry-on, make sure that everything can fit in a quart-size bag. Think about what you really need for your trip, a la Marie Kondo , and remember you can always buy things once you arrive at your destination.

Powders must be in 12oz containers or smaller. TSA placed new restrictions on powders in 2018. Ensure that your makeup, protein powder, and baby powder are in containers within that range, or put them into a checked bag.

Anything else has to go into a checked bag. If you can't part with your full-size products, they have to go into a checked bag to avoid getting tossed into the TSA product graveyard. If you're looking to save money, share one checked bag with your whole group.

Only empty water bottles will pass the TSA checkpoint. If you bring a refillable water bottle, make sure it's empty before you approach security. You can fill it up after you go through the checkpoint or buy water in the terminal.

There are exemptions. If you use a medication that comes in liquid, aerosol, gel, cream, or paste form and the container is larger than 3.4oz, it's exempt from the above rules. Similarly, if you're carrying baby formula, breast milk, or other liquid foods for your child, these are also exempt.

The TSA Liquids Rule for Carry-on Bags (3.4 ounces)

Tsa 3-1-1 rule, exceptions to the tsa liquids rule, tsa liquids rule for precheck, does tsa consider makeup a liquid, converting 3.4 oz to ml – how many ml is 3.4 ounces, what does 3.4 oz (100 ml) look like, converting 100 ml to oz – how many oz are in 100 ml, 100 ml to cups, 100ml bottle size – how big is a 100ml bottle, wrapping up: tsa liquids policy, more carry-on content:.

Before you finish packing to head to the airport, always double-check your carry-on bags and make sure you don’t have any bottles or other items that don’t comply with the TSA liquids rule, (known as the 3-1-1 rule).   

By the time the TSA finds that expensive bottle of perfume or lotion in your bag, it’s too late and you’ll have to say goodbye and hand it over to get through security and board your plane on time.  It’s happened to my family many times and could easily have been avoided with a quick check before leaving.

To help make sure this doesn’t happen to you, we’ve created this article that will tell you everything you need to know about the TSA liquids rule, including how much liquid is 100 ml, what are travel-sized bottles, what is considered a liquid, etc. Basically, all the stuff that could get confiscated when making your way through airport security.

What’s the TSA Liquids Rule?

The TSA liquids rule states that you can bring a quart-sized bag of liquids, aerosols, creams, gels, and pastes in your carry-on bag and through the airport security checkpoint. However, you are limited to containers that are travel sized and contain less than 3.4 ounces (100 milliliters) per item.

Items that are in packages or bottles larger than 100 milliliters (or 3.4 ounces) will have to go in your checked luggage .  In addition to larger liquids, any liquid that is more than 3.4 oz or 100 ml and is not contained in a secure, tamper-proof bag must be packed in your checked luggage.

Each liquid must be in a 3.4-ounce or less container (“3”), all containers must be placed inside one clear quart-sized plastic bag (“1”), and each passenger is only allowed one plastic bag (“1”).

There are 2 exceptions to the TSA 3-1-1 Liquids Rule

• Medications, and
• Infant/Child nourishment

Medications larger than 100ml

TSA allows larger-sized packages of medical liquids, gels, and aerosols in your carry-on. This also includes medical accessories such as freezer bags, pumps, syringes, etc. These items do not have to be in a plastic zip lock bag, but you will have to declare these items to TSA officers at the checkpoint prior to inspection.

Here’s a video that provides all the details you need about traveling with medication.

Formula, Breast Milk, and Juice

Formula, breast milk, and juice for infants and toddlers are allowed through the security checkpoint. These can be in quantities greater than 3.4 ounces or 100 milliliters and are allowed in carry-on baggage.

Similar to medications, just inform the TSA officer of what you have and remove the items from your carry-on bag so they can be screened separately from the rest of your belongings.

Ice packs, freezer bags, frozen gel packs, and other accessories required to cool formula and breast milk are allowed in your carry-on bag.

The TSA PreCheck Program allows registered travelers the ability to go through expedited screening lines at over 200 participating U.S. airports with over 80 participating airlines. Once you are approved in the program you don’t need to remove your 3-1-1 liquids from your bag.

Actually, you can avoid removing any of the following items during the screening process:

• 3-1-1 compliant bag
• Light jacket/Sport coat/outerwear
• Laptop / iPad from bag

To apply for PreCheck, go to tsa.gov/precheck . From here you can enroll and make an appointment online or walk in at any one of over 380 enrollment centers . It can take up to 30 days to obtain a TSA PreCheck known traveler number.

What does TSA consider a liquid?

According to TSA guidelines, any substance that is free-flowing or viscous is considered a liquid. This includes liquids, aerosols, pastes, creams, and gels.

According to the TSA, “Makeup in a solid or powder form is allowed in carry-on and checked bags with no quantity or size limitations. However, when packed in carry-on bags, makeup in a liquid, lotion, gel, paste, or creamy form, must be in containers that are 3.4 ounces or less. You can take as many travel-sized liquids as you can comfortably fit into one quart-sized, zip-top bag.”

When it comes to makeup, the following are some examples of liquid cosmetics:

• Nail polish,
• Moisturizers,
• Foundation,
• Mascara, etc.

How much is 3.4 oz?

Now that you understand the basic concepts of the TSA liquid rule, it may help to have an idea of what constitutes 3.4 oz or 100 ml, since most people don’t naturally know how big a 3.4-ounce container or a 100 ml bottle is.

So if you’re wondering exactly how much is 3.4 oz or how big is a 100 ml bottle, we will walk through that for you here.

3.4 ounces (oz) converts to 96.388 milliliters (ml). For purposes of simplicity, the TSA rounds this up to 100 ml

Most of the toiletries you would bring on a trip come in travel-sized packages that can be bought at any drug store or grocery store. These travel-sized items are typically 3 ounces (90 ml) and generally provide enough lotion, shampoo, or toothpaste for a 5-day trip. If you’ll be traveling longer, you may need to stock up on a couple of extra bottles or plan on purchasing more upon arrival at your destination.

100 milliliters (ml) converts to 3.3814 ounces (oz). For purposes of simplicity, the TSA rounds this up to 100 ml

100 milliliters (ml) converts to .422675 cups, so it’s just under 1/2 cup.

A 100 ml bottle is fairly small. To give you a visual, look at the image below that shows a 500 ml water bottle vs. a 100 ml spray bottle. The 100 ml bottle is about 3 inches tall and the water bottle is about 8 inches tall.

Hopefully, this guide will give you a better idea of what the TSA considers a liquid and what size they will let you bring on your carry-on. Knowing this information in advance can save a lot of headaches at the airport!

TSA Liquid Rules Ultimate Guide (3-1-1 Explained) [2023]

Bringing your liquids through airport security is not always as straightforward as you might think.

There are several rules that apply when bringing your liquids through airport security checkpoints and, yes, many are obvious to those of us blessed with a shred of common sense.

But in some cases there are some less obvious restrictions that could apply to your liquids.

And when you start talking about things like baby essentials, medications, and liquids like alcohol, there are many lesser-known rules and exceptions that come into play.

Violating these rules can sometimes mean slowing down the flow of the screening checkpoint (something we all should want to avoid) but in other cases it could mean violating the law and you basically becoming an airport criminal.

And nobody wants that.

So it’s a good idea to get acquainted with how these rules work and in this article, I’ll give you a detailed breakdown of the 3-1-1 rule and also talk about the many different types of exceptions and additional rules that apply to different types of liquids such as medications and alcohol.

What is the TSA Liquids “3-1-1 Rule?”

The TSA Liquids 3-1-1 Rule states that you can only bring liquids in containers no larger than 3.4 liquid ounces (100 milliliters) and that all of your liquid containers must fit “comfortably” into one clear, quart-size bag.

Where does the 3-1-1 come from?

It’s just an easy way to memorize the different requirements that make up the rule and I’ll hit on those below.

3.4 fluid ounces or (100 mL)

The “three” indicates that your liquids must be contained within a container no larger than 3.4 fluid ounces or (100 ml).

(TSA uses 3.4 ounces because it’s easier to remember but really  100 ml comes out to 3.3814 fluid ounces. )

One of the biggest things that people get confused about is that the 3.4 ounce requirement applies to the size of the container and not the liquid within the container.

So let’s say that you have a 6 ounce container with only 2 ounces of fluid inside.

You may think that because you have under 3.4 fluid ounces of liquid, you are good to go but because your container is larger than 3.4 ounces, you cannot bring that through TSA.

The other big thing to know is that this refers to fluid ounces which relates to volume and is very different from ounces used for weight.

Some products like honey could weigh 4 ounces but still fit inside of a 3.4 fluid ounce container. It helps to know how to convert ounces/grams to fluid ounces .

1 quart-sized resealable bag

The first “one” means that your liquids must fit within 1 quart-sized resealable bag. Typically, this will be a clear Ziploc bag which just makes things easy for everybody.

The key thing to note here is that the containers must fit “comfortably” inside this resealable bag.

What does “comfortably” mean?

It basically just means that the bag is not bursting at the seams. (Think about how a pair of jeans should fit when you’re being honest with yourself about your waist size.)

If you are not able to easily reseal your bag, then your contents may not be fitting comfortably inside.

In such a scenario, it’s possible that a TSA agent could ask you to throw something out in order to allow your bag to comply with the rules.

In my personal experience, I have not seen a lot of TSA agents enforce the “comfortable” requirement very strictly but if you have bottles poking out of your liquids bag, I could see that being an issue.

1 quart size bag per person

The last requirement is that you are allowed 1 quart size bag per person.

The easiest way to comply with this is to simply separate your liquids bag from your carry-on and have one liquids bag in your bin when going through security.

Otherwise, it could look like you are trying to bring through two bags of liquids.

The best packing tip I have for this is to keep your liquids bag at the top of your carry-on so that you can easily retrieve it.

There’s nothing worse than scrambling to find that liquids bag while trying to get ready to go through a screening checkpoint.

TSA Pre-Check liquids rule

TSA Pre-Check allows you to bypass the main security line and pass through a screening line that is usually much shorter and quicker. This also means avoiding the full body scanner in many cases. It basically makes you a VIP when it comes to airport security checkpoints.

If you have TSA Pre-Check , you can take advantage of several benefits including things like:

• Shoes can stay on
• Belt can stay on
• Light jackets can stay on
• Laptops allowed to stay in bag
• Liquids (3-1-1) can stay in bag

That last perk is the most relevant to the liquids rule as you will not have to remove your liquids bag and place them in one of the bins when going through security. You can simply leave them in your carry-on and pass through the metal detector without any issue.

I highly recommend that you look into getting Pre-Check in order to expedite your security screening. It will only cost $78 for five years and all you have to do is pass a background check. You can also get it if you are approved for Global Entry ( read how to get approved here ).

New hand sanitizer liquids rule

Due to the ongoing threat of coronavirus and the potential threat of spreading germs throughout airports and aircraft, TSA recently implemented a change with respect to hand sanitizer.

Passengers will now be allowed to bring one hand sanitizer bottle up to 12 ounces. These larger bottles will be screened separately so just be aware that it could add some extra time.

What exactly is a “liquid?”

In some cases, what constitutes a liquid will be very clear.

For example, it’s pretty much common sense that water inside of a water bottle is a liquid. The same applies for cologne, mouthwash, etc.

But liquids also can include less-obvious forms like aerosols, gels, creams, or pastes.

This means that several common items you would be bringing along for your trip could be considered a liquid like: toothpaste , lotion , sunscreen, shaving cream, shampoo , conditioner, and others.

You can find travel-sized products for most of these so it’s usually pretty easy to bring along items that comply with the TSA liquids rule.

Other items

You need to be mindful of other items that could be considered liquids like deodorant . For example, the following types of deodorants will be subject to the 3-1-1 rule:

• and Roll-On deodorants

Prohibited items

Just because you have something like an aerosol and it is in a container no larger than 3.4 ounces, that does not mean that you can bring it as a carry-on.

There are quite a few prohibited items like aerosol insecticide, bear spray, etc. that are not allowed as carry-ons. In fact, some of those items may not even be allowed on the plane at all. This is a good place to search if you are in doubt about whether or not you can bring a particular item.

Be aware that some items like hairspray may even have size restrictions when packed in your checked baggage.

Foods can also be liquids

One aspect of the TSA liquids rule that throws a lot of people off is that they forget many foods also qualify as liquids.

Here is a non-exhaustive list of food items that will fall under the liquids rule:

• Liquid chocolate
• Creamy dips and spreads
• Mashed fruits such as applesauce
• Jam and jelly
• Maple syrup
• Oils and vinegars
• Peanut butter
• Wet pet food
• Salad dressing
• Salsa and sauces

Basically anything that is usually poured, scooped, squeezed, slurped, or mashed will be considered a liquid for TSA purposes.

If your food is solid on the other hand , chances are you can bring it through.

TSA rules for liquid medications

The liquids rule provides exceptions for medical supplies and medications .

TSA allows larger amounts of medically necessary liquids, gels, and aerosols in “reasonable quantities” than your 3-1-1 allowance.

You do not have to have a prescription for these items but keep in mind that you need to comply with state laws regarding prescriptions and controlled substances.

This leaves two questions often to be asked and answered.

The first is what is considered “medically necessary?”

For example, is contact lens solution medically necessary?

It seems the answer to that is probably yes given the TSA states, they allow “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip” on the page regarding contact lenses.

So if in doubt check the website and then inquire with AskTSA if you still don’t know.

The second question is what is considered a “reasonable quantity?”

What is deemed as a reasonable quantity is a subjective determination.

According to the TSA, you should bring what’s necessary for the duration of your trip (e.g., seven days) plus a day or two just in case things get delayed or canceled.

If you stick to what you think will be necessary for the duration of your trip, I don’t think you will often run into trouble. But if you’re bringing a six month supply of medication on a four day getaway, that’s when you might start to run into trouble if questioned.

TSA states that you must declare them to TSA officers at the checkpoint for inspection.

You also want to remove these from your carry-on so that they can be screened separately from your belongings. (You do not have to put your liquid medication in a plastic Ziploc bag.)

Just be aware that if one of your liquid items declared as medically necessary sets off the alarm, it may require additional screening and may not be allowed.

Baby essentials

You are allowed to bring formula, breastmilk, and juice for infants or toddlers in “reasonable quantities” through airport security. According to the TSA, reasonable quantities for baby essentials typically means the duration of the flight.

When bringing these items through security, be sure to separate these from your carry-on bag so that they can be screened separately from the rest of your items.

If you are carrying liquids in excess of 3.4 ounces, you are advised to inform the TSA officer at the beginning of the screening process that you have excess liquids. You can do this when you are unloading your items into the bin.

In many cases, excess liquids will be screened by x-ray.

It’s also possible that an officer may ask you to open up the container and potentially even transfer a small quantity of the liquid for testing.

If you are worried about the effects of an x-ray machine on your liquids, The Food and Drug Administration states that there are no known adverse effects from eating food, drinking beverages and using medicine screened by X-ray.

If that is not good enough assurance for you, you can ask to avoid the x-ray machine.

Additional steps may be able to be taken to clear the liquid but the traveler will likely have to undergo additional screening procedures which could include a pat down and a thorough screening of all of your carry-on property.

You will also be allowed to bring along ice packs, freezer packs, frozen gel packs and other accessories required to cool formula, breast milk and juice.

If these are in a partially frozen state or perhaps appear like a slushy they will be subject to the same screening as described above.

Other permitted baby items include gel or liquid-filled teethers, canned, jarred and processed baby food.

Just always be aware that these items may have to undergo additional screening.

TSA liquid rules for alcohol

Bringing alcohol through TSA presents a number of different challenges.

First, your alcohol in most cases will have to comply with the liquids 3-1-1 rule. This means that you won’t be able to bring in regular bottles of liquor or beer.

It is possible to find small bottles that are under 3.4 ounces (mini-liquor bottles are often around 1.7 ounces, so this means that they are small enough to be brought on the plane as a liquid).

But contrary to what many people think, it’s also permitted to bring your own alcohol in one of your own containers.

The catch is that there are specific restrictions about what type of alcohol is allowed on board and that can be allowed as a carry-on. You really need to make sure that you are abiding by these rules because you could be violating federal law otherwise.

The first regulation to know is that alcohol beverages with an alcoholic percentage above 70% (140 proof) is never allowed on the plane . In fact, alcohol with such a high alcohol percentage is considered a hazardous material.

If the alcohol content is above 24% but not above 70% then the alcoholic beverage must be in its retail packaging. A lot of popular alcoholic beverages for within this range. Here are some  ranges  for the alcoholic content of some common beverages:

Alcohol Percentage Content

• Vodka | ABV: 40-95%
• Gin | ABV: 36-50%
• Rum | ABV: 36-50%
• Whiskey | ABV: 36-50%
• Tequila | ABV: 50-51%
• Liqueurs | ABV: 15%
• Fortified Wine | ABV: 16-24%
• Unfortified Wine | ABV: 14-16%
• Beer | ABV: 4-8%
• Malt Beverage | ABV: 15%

And finally, one of the most important things to remember is that you are not allowed to serve yourself your own alcohol when flying.

Instead, you must request a flight attendant to serve you the alcohol or else you will be violating FAA regulations. Some flight attendants will happily serve you your own beverage but others will not be so inclined.

If you purchased alcohol at duty free store, different rules apply in that scenario. Basically, you can bring your duty free alcohol through TSA security but you have to comply with three separate requirements:

• The duty free liquids were purchased internationally and you are traveling to the United States with a connecting flight.
• The liquids are packed in a transparent, secure, tamper-evident bag by the retailer and do not show signs of tampering when presented to TSA for screening.
• The original receipt for the liquids is present and the purchase was made within 48 hours.

Read more about this rule  here .

Checked baggage liquid rules

Many times, you can simply place your liquids in your checked baggage and not have to worry about that pesky 3-1-1 rule.

This is usually the way to go on longer trips when you might be bringing large quantities of things like shampoo or shaving cream.

But as mentioned above, you still need to make sure that the type of liquid is allowed on a plane. Certain materials may be considered hazardous and you could be violating the law by bringing those on board.

If you are loading up your checked baggage with a bunch of liquids, make sure that you double bag if there is potential for the liquids to spill!

TSA Liquid Rules FAQ

The TSA 3-1-1 rule does not apply to checked baggage. However, there are some restrictions on what liquids can be transported in your checked baggage. There may also be limitations on the quantity of liquids when it comes to importing large quantities of things like alcohol. At some point, you might have to obtain a license for certain goods.

TSA definitely enforces the liquids rule and I would recommend not trying to circumvent the rule. It’s possible that an agent may be more lenient than another in certain circumstances but I would always assume that an agent will be enforcing strictly so that I don’t run into any unexpected issues.

TSA has the rules in order to detect potential explosives and other harmful materials that exist in liquid state.

The same liquid rules apply for both domestic flights and international flights. One difference that you might encounter is when you purchase duty free goods before an international flight. See the duty-free section above for more details. Also, when flying internationally it is recommended that you get to the airport extra early. It is possible that you could get hit with SSSS and be forced to undergo a heightened security screening, so always plan out extra time.

While you might view your makeup as special, there are no special rules for your makeup when it comes to TSA. They must abide by the same 3-1-1 rule explained above. Read more about makeup rules here.

No, you do not have to take out your liquids if you have TSA Pre-Check.

The same TSA liquids rule will apply to all airlines. So if you’re flying American or Delta, the rules will be the same as if you were flying Southwest or United. With that said, some airlines do have some differences in how they handle acceptable baggage so you should make sure to read up on the latest baggage policies for the airlines.

If you are traveling from an “international last-point-of-departure” to the U.S ., powder-based substances in carry-on baggage greater than 350mL or 12 oz. may require additional screening. If your substance is over 12 ounces and cannot be cleared it will not be allowed onto the aircraft cabin. TSA recommends that you transport powders in your checked baggage.

TSA has several rules you need to follow when it comes to drinking liquids through airport security. The most well-known is the 3-1-1 rule but there are other considerations you need to think about like foods that might trigger the rule and exceptions for medical and baby essentials. In the end, try to be as reasonable as possible with what you are bringing through and you will run into few problems.

TSA Liquid Limits: What You Can Carry and How Much You Can Bring

The tsa allows liquids under 3.4 ounces in your carry-on—but what’s considered a “liquid” isn’t always obvious..

• Copy Link copied

Don’t forget to remove your liquids when going through TSA screening.

Whether you’re a carry-on-only kind of person or not , knowing the Transportation Security Administration’s (TSA) liquid limits is essential for anyone who travels by plane in the United States. Yet understanding which of your toiletries, foods, and other items even count as “liquid”—let alone how best to pack them—can get confusing. Use this guide to understand the TSA’s rules and restrictions about liquids, common exceptions, and tips to help ensure your next airport security screening goes smoothly.

What is the TSA liquid limit?

The TSA’s liquid limit for carry-ons—known as the 3-1-1 rule—allows travelers to pack liquids, aerosols, gels, creams, and pastes under 3.4 ounces (100 milliliters) in their carry-on bags. Passengers are allowed up to one quart-sized bag per person , or roughly nine 3.4-ounce containers in a single quart-sized bag. Anything more will have to go in a checked bag or risk being tossed out.

If your liquids are stored in containers larger than 3.4 ounces, even if there’s only 3.4 ounces left inside the bottle, you can’t bring them through security.

Completely empty bottles, such as your reusable water bottle , are allowed through the TSA checkpoint since (spoiler alert!) they don’t contain any liquids at that moment.

Which toiletries TSA allows in your carry-on

The TSA allows all of the following common toiletries in your carry-on only in containers that are 3.4 ounces or less:

• Shampoos and conditioners
• Lotions and sunscreen
• Gel hair products

In other words: yes, you can bring toothpaste, deodorant, and sunscreen through TSA checkpoints but only if they are in travel-sized containers.

Powders and powder-like substances, including baby powder and some makeup items, aren’t restricted in your carry-on bag. But if you’re carrying more than 12 ounces (350 milliliters) of a powder, you’ll need to place it in a separate bin for X-ray screening, and it may be subject to additional screening—so it’s a good idea to budget an extra few minutes at the security checkpoint if you think this might happen.

Tips for packing your toiletries in your carry-on

To comply with TSA regulations, invest in small, reusable toiletry bottles, like these capsules by Cadence.

Especially if you don’t have TSA PreCheck , it’s helpful to pack all of your toiletries in a quart-sized (or smaller) clear plastic toiletry bag for screening. Although improved airport technology means that far fewer air passengers (both in PreCheck and non-PreCheck lines) will have to take their liquids out out of their carry-on, it’s still helpful to have all of your liquids in one bag just in case you get pulled aside for additional screening. For an upgrade from that large Ziplock, we recommend the standard-sized Clarity Jetset Case from Truffle ($88), which has a clear window panel and is comparable in size to a quart-sized bag.

Since toothpaste is considered a liquid, paste, or gel by the TSA, most of us toss those tiny one-ounce tubes in our carry-on bags. However, if you want to ditch the hard-to-recycle packaging, consider toothpaste tablets, an ecofriendly alternative that’s not subject to the 3-1-1 rule. We like Humankind’s fluoride toothpaste tablets ($12), which resemble small mints and turn to paste when you crush them between your teeth. Matador has also recently released a reusable toothpaste tube ($10), which you can fill (and refill) with your regular toothpaste.

For travel toiletries that are easy to rebottle (like shampoo or body wash), consider investing in reusable bottles or containers so you can always keep your preferred brand on hand. Some of our favorite TSA-approved toiletry bottles include:

Buy Now: GoToob three-pack of 3.4-ounce bottles, $30, rei.com

These easy-to-fill, leakproof silicone tubes are ideal for shampoos, conditioners, lotions, and body washes. GoToob’s line comes in a variety of sizes, ranging from 1.7 to 6 ounces, and are easy to clean between refills.

Matador FlatPack

Each three-ounce, TSA-approved bottle is made from a durable, waterproof, nylon-based fabric. Like GoToob, they’re leakproof and easy to fill, but thanks to their flexible, fabric-like design, they will shrink to their contents, taking up less space in your pack. >> Read the full review of the Matador FlatPack

The refillable travel containers by Cadence are small, leakproof “capsules” that click together with magnets. At 0.56 ounces, they’re best for makeup and toiletries you don’t need much of—like a weekend’s worth of shampoo or a week of that under eye cream you only need a dab of.

Foods are subject to liquid limits

The TSA’s 3-1-1 rule applies to food too, meaning you’ll need to make sure any foods that count as liquids, gels, or pastes (like yogurt, peanut butter, pâté, jams, or that tasty pimento cheese spread you tried to bring home from Charleston) are less than 3.4 ounces or packed in your checked bag. There are some exceptions, like frozen foods and juice for babies, and the TSA’s website is the best resource to check for specific items.

Exceptions to TSA’s liquids rule: Full-sized liquids that you can bring through security

The TSA has several important exemptions to its liquids rule. You’re allowed to bring full-sized bottles of the following:

Hand sanitizer: Due to the coronavirus pandemic, the TSA currently allows travelers to bring up to 12 ounces of hand sanitizer in their carry-on bags. These will be screened separately.

Medication: You’re allowed to bring medically necessary liquids, aerosols, and gels through security. This also includes the ice or gel packs you may need to keep your medications cool. You are not required to store these items in a plastic, resealable bag, but you should remove them from your luggage and let the TSA officer know what you’ve packed.

Baby formula and breast milk: Like medication, you can bring freezer packs to keep these items cool, and you should remove them from your luggage and notify an agent when you go through security. More baby-related exceptions? Gel or liquid-filled teethers and canned or jarred baby food.

Of course, the final decision on whether an item is allowed through the checkpoint rests with the TSA officer.

If you’re ever unsure about a specific item, the TSA’s website has a handy, searchable list of prohibited and allowed items worth checking before you travel. You can also now text the TSA with your questions.

TSA Liquids Rule: The 411 on the 3-1-1 Limit

Despite the TSA’s 3-1-1 liquids rule having been in existence for over ten years, many people are still a bit confused by, or just want to double check that they are in compliance of, the rules regarding bringing liquids on a plane. Many people may think that some things with liquid in it (like makeup) or a container that’s bigger than 3.4 ounces yet has less than that amount in it still qualify (spoiler alert: they don’t). So let’s run through every scenario we can think of and determine whether it’s allowed.

what does the 3-1-1 Liquids rule mean?

People know this phrase, but many are unsure of what it specifically means. Well, according to TSA rules, the “3” stands for 3.4 ounces (100 milliliters) of liquid, the first “1” stands for one clear zip-lock bag holding your 3.4 ounce containers, and the second “1” means per traveler. So there you go, you are limited to one bag with as many 3.4 ounce containers as can fit into your carry-on .

3 = 3.4 ounce containers (you may not Carry-on larger containers with less than 3.4 ounces of liquid)

1 = 1 clear zip-lock bag (with as many 3.4 ounce containers as you can reasonably fit in), 1 = 1 per person (no exceptions).

If you would prefer not to do any math, we recommend this TSA approved set of containers and plastic bag to avoid any confusion.

Obviously, if you are checking your bag then you can place full-size liquids in there, but those should still be in a plastic zip-lock bag as well, if for no other reason than the cap might come off and everything gets all over your clothes.

Why was this rule implemented? A terrorist plot in the U.K. attempted to carry liquid explosives onto a plane, disguising them as soft drinks. This led to lasting legislation in the United States, requiring everyone to significantly alter their travel methods, especially when it came to soaps and shampoos. But far more things with liquid in it are subject to the same rule than people realize.

are there 3-1-1 rule exceptions?

Yes. There are really only two of them, but they are crucial to some passengers – and no, TSA Precheck status is not one of them. One of them is medications . To avoid any problems, make sure these medications are clearly marked, separate them from other toiletries so that they aren’t mistaken as such, and inform the TSA screening officer of them. They don’t have to be in a zip-lock bag, and you’re allowed to bring necessary accessories (bags, pumps, syringes, etc.) on board with you as well. The TSA obviously still has to do their job and X-ray your items, and they may ask you to transfer the medication from its bottle to a clear separate container. If you don’t want them to be scanned, then the alternative is to go through a pat-down procedure.

The second exception are things necessary for your children , such as formula, breast milk and/or juices. The requirements here are generally the same as they are for medications; mark them, separate them, inform the TSA. The screening officers do still have to inspect them just to make sure there aren’t any concealed prohibited items, and you can request alternate methods of search other than an X-ray. Some specialty considerations that you are allowed to bring include: gel or liquid-filled teethers, canned or jarred processed baby food, as well as ice packs or gel packs.

It should be noted that duty free items purchased internationally are also allowed as long as they are in a cleat tamper-evident bag and you have the receipt showing that it was bought less than 48 hours prior to your flight. So now that you know what’s excepted when it comes to accepted liquids, where does the TSA draw the line?

what are the tsa carry-on liquid rules?

If you’ve traveled you’re well aware of this, but if you haven’t, it’s important to know that the liquids in your zip-lock bag must be taken out of your luggage and placed in a separate bin to be X-rayed. Now that you know the second most crucial thing about airline travel (the first being wear clean socks) here is a brief list of all the allowable liquids so long as they are in a 3.4 ounce container and inside that clear bag:

• Conditioner
• Some aerosols, such as: antiperspirants, shaving cream, hair spray, and other toiletry items. We’ll discuss the prohibited aerosols in a minute.
• Liquid makeup, such as eyeliner, nail polish and foundation must comply with the 3-1-1 rule. Powder cosmetics are accepted with no limits.
• Alcohol, but DO NOT drink it on the plane.

Here now is a much longer list of the liquids and gels that are NOT allowed on an airplane , even if it is in a 3.4 ounce or less container:

• Aerosols that aren’t personal care items, such as: air fresheners, self-defense sprays and other flammable aerosols. Basically, if it’s not meant to be sprayed on your body, it’s not allowed.
• Vaping devices (many of these are liquid-based)
• Any paint, gel or liquid that is flammable, such as lighter fluid or gasoline
• Gel-type candles
• Spillable batteries
• Paint thinner

A couple of these things, such as the candles, are allowed in your checked baggage, but for the most part all of these things aren’t allowed in any of your bags. There are extra things to consider as well. Say you’re traveling abroad and you buy a snow globe for your child as a present. Well that thing better have less than 3.4 ounces of liquid in it, otherwise you’ll have to risk putting it in your checked baggage.

At the end of the day, the TSA security officer has total discretion about whether or not to allow something of yours through security. But if it’s in a 3.4 ounce or less container, in a clear zip-lock bag, and is not flammable, you’re probably good to go.

44 Comments

Is there a specific size limit for the Ziploc bag? Also, can I carry on “alcohol Inks” it’s a liquid crafting ink. Less than 1oz each.

Does powder makeup have to be in the quart bag or no?

May I bring gummy vitamins and medications on the plane? I can’t take the pill form…

Yes, you can bring them onboard (as long as they are not liquid vitamins that are over the limit)

Can one bring a jar of salsa in a carry-on?

Unless it’s the world’s tiniest jar of salsa, probably not. Salsa is a liquid and if it’s more than 3.4 ounces or 100 milliliters, you can’t bring it on board the plane. Personally I’d go for the ounces over 100ml because technically that’s only 3.3814 ounces ?. You can always pack it away safely on your checked luggage, just be sure to wrap it as safely as possible. Bubble wrap is always a good idea for glassware. If it’s just a plastic container, I suggest putting that in a plastic bag just in case.

Can I bring my purse and a carry on bag on the plane? Also, can I bring my 2 small bottles of pills Metoprolol (for heart) and Omeprazole (acid reflux) in my purse or carry-on bag?

Most airlines alow both a carry on and a personal item (the purse would be considered a personal item). Medication in pill form should be fine, if it’s a prescription I would make sure to bring documentation.

How about coffee mini creamers ?

If you get the creamers inside the terminal (i.e. from vendors) they should be fine. Otherwise, they would have to go in the quart sized bag.

Can I bring essential oils of 5 Mil in my carry on?

Can i bring a quart bottle water frozen – ice/not slushy thru the checkpoint? Great article!

My TSA approved containers to carry shampoo and such are actually labeled 4.0 oz. is this going to b ok? Purposely purchased these because it said TSA approved!!

if my shoe inserts, prescription orthodics, have gel in them can I wear them on the plane? They are expensive, I wouldn’t want them to be confiscated.

Orthotics will be fine.

Reference the duty free info. I purchased duty free alcohol and upon entry into the US and re-entry thru TSA at IAD, they insisted they had to open the sealed duty free bag to double check all items. Apparently, double check meant running them through a spectrometer or something. Since one of the items was similar to Baileys in a non-clear bottle and a thick non-clear liquid, it didn’t pass the test. My choices were confiscation or try and mail it back outside TSA. Luckily, United helped me package it as another checked bag. The point I’m making is unless I was being scammed, don’t assume everything purchased in duty free will clear TSA. BTW, the TSA website made no mention of this policy as I’d checked.

sorry may i bring all these items on the plane i missed typed the prior email. may i bring on the a bag of cookies unopened, bag of chips unopened and a 1 liter of soda unopened or a liter of bottle or can water brought at my local grocery store? or do i need to purchase everything behind TSA security check in

You cannot bring liquids on the plane. 1 liter of soda far exceeds the 3 ounce rule. The food should be fine.

I have the perspiration drug of Testosterone that was prescribed by my doctor. I will need a syringe to inject this medication. Will I be able to bring this in my carry-on?

Yes, but it is a good idea to get a note from your doctor.

I have prescription medication “Androl Gel and I am sure it is greater than 3.5 oz. and an alcohol based gel. Can this be kept with my other medications in my carry on?

Medications are allowed in greater quantity than other liquids and gels. I would bring a note or prescription from your doctor just to be sure.

I wish to carry 5 packets of garden seeds bought at a local nursery to India in my checked baggage. Is it allowed? Thank you.

You may need to declare that at customs.

I am taking Canadian Maple syrup as gifts (300ml bottles) in my checked luggage. Can I wrap them well in bubble wrap or do they have to be visible in a clear bag?

They do not need to be in a clear bag in checked luggage, although putting them in a watertight bag isn’t a bad idea in the event they break.

can i bring an un opened package with glade plug ins

If there is liquid in them, they may need to go in checked luggage.

Almost all references to the 1-quart bag dimensions are just width and height. What about the depth? Or is the overall volume of 1 quart the ultimate bottom line? If so, what is that volume?

The volume is 1 quart. They are standard sized bag.

does mascara fall under the 3-1-1 rule?

Chris, common sizes of mascara and similar products are exempt from the 3-1-1 rule. Now if you have a monster sized mascara, then I would put it in a ziptop bag.

Can I bring more than one liquor bottle which are less than 100ml or 3.4 oz?

Travelers may carry as many 3.4 ounce bottles of liquid (mini bottles of liquor are 1.7 ounces) that fit comfortably in one, quart sized, clear plastic, zip-top bag. Comfortable means that the bag will seal without busting at the seams. One bag is permitted per passenger. Travelers may take up to five liters of alcohol with alcohol content between 24% and 70% per person as checked luggage if it’s packaged in a sealable bottle or flask. Alcoholic beverages with more than 70% alcohol content (140 proof), including 95% grain alcohol and 150 proof rum, cannot be packed in checked luggag

Can I hand carry chicken eggs?

You may be able to, but the final word rests with the security agent that day. If you do, pack them in plain egg cartons to they are easy to take out and inspect. If they are not fertile, offer to let them scan them. Be courteous and understand you may have to toss them.

Can I carry on 10 hand made cookies, tightly wrapped in saran wrap in a bag so easy to view to inspect. About 10–they are hand made holiday cookies.

Yes. But save me some.

small tube of toothpaste, crystal light individual packets, instant coffee individual packets Are these items allowed?

Toothpaste falls under the 3-1-1 rule, the rest of the items are allowed.

Can I bring my hair straightener ( flat iron ) with me on the plane?

Yes you can Diana.

May I carry on a 1# (one pound) bag of Dunkin Donuts ground coffee?

Yes. No issues with coffee, no matter the brand.

TSA liquids rule: What to know about 3-1-1 before you head to the airport

Editor's Note

We've all been there: You're waiting in the Transportation Security Administration line, only to hear agents call for a "bag check."

Oftentimes, it's because a traveler has a liquid product in their carry-on that exceeds the allowed limit.

The ensuing process can slow things down, particularly on the busiest travel days. Agents typically have to inspect the bag, determine what the prohibited item is and allow the traveler to decide whether to discard the item or take it back to their car.

But what exactly are the TSA liquid rules, and why do they exist? And, most important, what does this mean for packing ahead of your next trip?

Here's a quick rundown.

TSA liquids rules: Why do they exist?

The TSA's restrictions on liquids date back to 2006 when a thwarted terrorism plot overseas prompted the agency to limit large quantities of liquids, gels and aerosols in carry-on bags.

Scores of other countries around the world took similar steps in the name of aviation security. You'll find comparable rules as you travel internationally — though the U.K. is moving toward removing these restrictions.

What is the TSA 3-1-1 rule?

The TSA's ban on liquids — or at least large quantities of them — is governed by what's known as the " 3-1-1 rule ."

The decades-old policy states that:

• Liquids must be in containers no larger than 3.4 ounces, or roughly 100 milliliters (that's the "3").
• All containers must be placed in one clear, quart-size plastic bag ("1").
• Each passenger is only allowed one such plastic bag ("1").

These rules govern liquids, gels and aerosol products ranging from toothpaste to shampoo, conditioner, mouthwash and sunscreen — among other products.

Liquid products larger than 3.4 ounces must be placed in a checked bag. That even applies to those large shampoo containers with just a tiny bit of shampoo left, per TSA policy.

Exceptions to the TSA's 3-1-1 policy

There are a few exceptions , though.

The TSA will allow you to bring "medically necessary" liquids, gels and aerosols "in reasonable quantities" for your flight. However, you must declare those items to security officers at the checkpoint for inspection.

The agency asks travelers with larger amounts of medically necessary liquids to remove them from the carry-on bag and place them in a bin or bowl. The TSA has a variety of alternative screening methods it can use.

What can you bring through a TSA checkpoint?

You can bring creamy cheeses, liquid chocolate, liquid coffee, creamy dips and spreads, gravy, honey, hummus, ice cream, jam, jelly, juice, syrup, peanut butter, salad dressing, sauce, salsa, soda, soup, and yogurt as long as they are in a container of less than 3.4 ounces, according to the TSA .

You can bring your water bottle with you, even if it weighs more than 3.4 ounces — as long as it's empty. This can also be a great way to save money at the airport since many now have post-security filling stations for reusable water bottles.

When in doubt, consult the TSA's list of what you can carry through the airport and check with your airline.

Or, better yet, download the MyTSA app . It contains a "Can I Bring?" section, allowing you to look up items and find out whether they're allowed outright, restricted to 3.4 ounces, permitted only in a checked bag, permitted only in a carry-on bag or prohibited altogether.

Liquids, Non-solid Food & Personal Items

You can make your security screening experience quicker and easier by packing your liquids, non-solid food, personal and toiletry items properly.  At the airport, these items are referred to as “liquids, aerosols and gels.”

Below you will find information on various items that fall into these categories, a list of items that are exempted from restrictions, and tips on how to pack all of them. 

On this page

Examples of liquids, non-solid food and personal items that are liquids, aerosols and gels, how to pack your liquids, non-solid food and personal items, liquids/non-solid food, personal items.

• soft drinks
• bottled water
• maple syrup
• conditioner
• liquid soap
• insect repellent
• liquid/gel based hand sanitizers
• creams/lotions
• liquid based cosmetics (e.g. mascara, liquid foundation, liquid eyeliner)
• static remover
• sunscreen spray
• shaving cream
• aerosol deodorant
• aerosol cheese strings
• hair styling gel
• mashed potatoes
• peanut butter
• chocolate spread
• cheese spread
• maple spread
• shaving gel
• gel-based deodorant
• gel-based cosmetics (e.g. gel blush, gel lip products)

Please note that if an item that is illegal in Canada (e.g. pepper spray) is found at a screening checkpoint, CATSA is required to notify the police.

• Containers of liquids, non-solid food and personal items in your carry-on must be 100 ml/100 g (3.4 oz) or less . All containers must fit in one clear, resealable plastic bag no more than 1L in capacity. The bag must be transparent so screening officers can easily see the contents.
• Each passenger is allowed a single 1 L bag containing liquids, food and personal items. The approximate dimensions of a 1L bag are 15.24 cm by 22.86 cm (6 in. by 9 in.) or 20 cm by 17.5 cm (8 in. by 7 in.).
• At the screening point, take your plastic bag out of your carry-on and place it in a bin.
• Any containers over 100 ml/100 g (3.4 oz) can be placed in your checked baggage as long as they are not prohibited items. 
• Avoid packing gifts and souvenirs containing liquids, aerosols and gels in your carry-on. These include: liquor, wine, beer, snowglobes, cans of condensed soup, maple syrup, perfume, and lotion. Put them in checked baggage or ship them separately.
• Beverages: Drink or discard any beverages in containers of more than 100 ml before you get to security screening checkpoint.  This includes water in your personal water bottle. You can refill your container once you pass through security.
• Duty-Free Alcohol: Be sure you know the rules for bringing duty-free alcohol as part of your carry-on baggage.
• Non-solid food (e.g. yogurt, pudding, peanut butter, jam) in your carry-on must be in containers of 100 ml or less. All containers must fit in the same clear, closed, resealable 1 L plastic bag, along with all other containers of liquids, food or personal items you are carrying.
• Food over 100 ml that is normally a liquid or gel but has been frozen solid will not be allowed to pass through security in your carry-on. In order for a food to be considered a solid, it must be solid at room temperature.
• Solid food with less than 100 ml of liquid: Canned or jarred goods containing both solids and liquid that clearly contain less than 100 ml of liquid (e.g., can of tuna) are allowed. These items must fit in the same clear, closed, resealable 1 L plastic bag with all other containers of liquids, food or personal items you are carrying. 
• Food in checked baggage:  Both solid food and non-solid (over 100 ml) can go in your checked baggage; however, some restrictions may apply.

Did you know?

You can bring solid food in both carry-on and checked baggage. See Travelling with Food Items  for more detail. 

You can pack alcoholic beverages (including homemade wine and beer, and commercial products) in your checked baggage if:

• The percentage of alcohol by volume is 70% (140 proof) or less.
• The quantity does not exceed five litres per person for alcoholic beverages between 24% and 70% alcohol by volume.

Alcoholic beverages containing 24% alcohol or less are not subject to limitations on quantities. 

Duty-free alcohol: See Duty-Free Purchases .

Check the Canadian Border Services Agency website for personal exemption amounts on alcoholic beverages.

Personal items are allowed in carry-on baggage if they comply with the liquid restrictions. Some restrictions also apply to personal items in checked baggage.

The following items are allowed in limited quantities in your checked baggage:

• Insect repellent (limit of one aerosol canister per person)
• Aerosol items that are toiletry articles (e.g. hair spray, perfumes, cologne, aerosol deodorant)

Aerosols are subject to a maximum limit of 500 ml/500 g per container , with a total net quantity not exceeding 2 L/2 kg. Release valves on aerosols must be protected by a cap or other suitable means to prevent inadvertent release of the contents.

Some items are exempted from the 100 ml or 100 g (3.4 oz) limit and do not have to be placed in a plastic bag. However, you must declare these items to the screening officer for inspection. The exceptions are:

• Baby food/drink: If you are travelling with an infant younger than two years of age (0-24 months), baby food, milk, liquid formula, water and juice are allowed in quantities greater than 100 ml .
• Breast milk: Passengers flying with or without their child can bring breast milk in quantities greater than 100 ml
• Prescription medicines are allowed.
• Essential non-prescription medicines , such as homeopathic products, pain relieving medication, cough syrup, decongestant spray, gel-based nutritional supplements, saline solution or eye care products, are allowed. 
• COVID-19 test kits are permitted without restrictions in carry-on and checked baggage.
• Gel and ice packs are allowed, if they are needed to treat an injury, to refrigerate baby food, milk, breast milk, formula, water and juice for infants younger than two years of age (0-24 months), or to preserve medically necessary items or medication
• Liquids/gels for diabetes: Juice or gels are allowed if you need them for diabetic or other medical conditions.
• Distilled water for CPAP devices: The distilled water needed to operate Continuous Positive Airway Pressure (CPAP) devices is exempt from liquid restrictions.

Documentation to support your medical needs or condition is not required; however, if you feel that it would help ease your screening, it should be presented to the screening officer along with your medically necessary items.

TSA Liquid Limits: Get the Scoop on What You Can Carry on and What You Should Check

To help safeguard travels, the TSA imposed the 3-1-1 Rule for liquid limits. 3-1-1 offers a simple way to remember these numbers:

• Individual liquid containers must be 3 .4 ounces (100 milliliters) or smaller.
• They must fit into one clear, resealable quart-size bag.
• There is only one bag allowed per passenger.

Everyone has been stuck at the security checkpoint during their jet-setting travels. Some may have had to say goodbye to their favorite perfume or hair products. Dealing with airport security can be one of the more daunting aspects of travel, from the Transportation Security Administration (TSA) liquid limits to the long lines and wait times. But with a few tips and the right info on what you can and can't bring on the plane, you'll be able to pack like a pro and fly through security.

If you know the rules, planning and packing for the TSA and the United Kingdom's Department of Transport should be seamless. These standards will help you and other passengers keep the lines moving. One rule that frequently confuses travelers is the 3-1-1 rule regarding liquids in carry-on bags. So, we're going to break it down for you and explain what you can carry on the plane, what needs to be stowed in checked luggage, and a few exceptions to the rules.

TSA 3-1-1 rule simplified

In 2006, security officials intercepted a plot to bomb an aircraft with liquid explosives carried on board. Since then, security agencies worldwide have limited the amount of liquids passengers can bring through airport security.

To help safeguard travels, the TSA imposed the 3-1-1 Rule for liquid limits, which requires all LAGs (liquids, gels, and aerosols) to be 3.4 ounces (100 milliliters) or less. All liquids must fit into a single, resealable, clear, quart-sized bag. Typically, passengers can fit seven or eight 3 oz. bottles in a bag.

3-1-1 offers a simple way to remember these numbers:

• Individual liquid containers must be 3.4 ounces (100 milliliters) or smaller.

Liquids must comply with the 3-1-1 rule to be packed in checked bags, or they will likely be thrown out at airport security. Some liquids, such as gasoline or other flammable liquids, are prohibited in checked and carry-on bags. The TSA's website provides a complete list of permitted and prohibited items.

The TSA and international airport security define LAGS as liquids, aerosols, gels, creams, and pastes. That means toothpaste, hair spray, hand sanitizer, perfume, peanut butter, shampoo, and mouthwash are all considered liquids by the TSA. If you can squeeze, spray, or spread it, it falls under the 3-1-1 rule.

Pro tip : Lipsticks and lip balms are considered solids, but mascara is a liquid.

What are the exceptions to the TSA fluid limit?

The TSA recognizes circumstances that require some passengers to carry more than 3.4 ounces of liquid in their carry-on bags. Exceptions are made for necessary items you would need during your flight and cannot be purchased after the security checkpoint.

TSA limit exceptions include:

• Prescription medication in original bottles or packaging.
• Medically necessary liquids and IVs.
• Baby formula and breast milk.
• Baby and toddler drinks, water, and food, including puree pouches.
• Ice, gel, or freezer packs used to keep breast milk, infant formula, or medically necessary items cool.
• Anything you purchase in the airport after security clearance is accepted on your flight.

You can bring over 3.4 ounces of these liquids on board, but you may undergo additional security screening. All prescribed medication (liquid or otherwise) should be clearly labeled to help you move through security quickly. Over-the-counter and non-prescription medications are not exempt from the 3-1-1 rule. Liquids are screened by X-ray, but TSA officers may also randomly test them separately for traces of explosives or prohibited items. If you don't want your exempt liquids to go through the X-ray, inform your TSA officer, and they will use alternative security measures to clear the items.

Liquid limits and restrictions for checked bags

The TSA has more lenient rules about liquids in checked luggage. You can carry creams, gels, drinks, and toiletry-based aerosols in your checked baggage. The TSA prohibits certain liquids that pose a public danger from checked and carry-on luggage. These liquids are prohibited in any amount, and their discovery during security checks can result in missed flights, arrest, or legal action.

Don’t travel with any of the following liquids:

• Alcoholic beverages over 70% ABV
• Aerosols that are not toiletries
• Flammable liquids
• Toxic liquids
• Insecticide
• Explosives/fireworks

The quart-sized bag

To keep things uniform and consistent, TSA instructs every passenger to put all of their 3-1-1 LAGs (liquids, aerosols, gels) in one resealable quart-sized clear bag (6 inches x 9 inches or 0.946 liters). Different brands may have slight variations of sizes, but TSA gives you some wiggle room regarding quart-size bag dimensions. If you're packing liquids in a travel toiletry bag, look for one that’s about quart-sized, or you run the risk of getting it confiscated. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, hand sanitizer, creams, shampoo, conditioner, mouthwash, and lotion. Unless you have TSA PreCheck or Global Entry , you must take out your baggies to display before they go through the X-ray machine.

Expert tips for packing liquids in carry-on bags:

• Prepare your liquids in advance and adhere to the 3-1-1 Rule.
• Source TSA-approved containers and quart-sized bags.
• Decant liquids into small travel-sized bottles.
• Use leak-proof containers and pack carefully to avoid spills.
• Buy some items like dry shampoo, solid soaps, perfumes, etc. instead of liquid.
• Pack large liquids in checked baggage.
• Pack your non-liquid toiletries separately to save space in your quart-sized bag.
• Keep your liquids in the baggie on top of your carry-on or purse for easy access at security. Once at the gate, you can always put them in your luggage.

USA vs international rules: how do they differ?

TSA works closely with international departments to maintain flight security standards abroad. If you fly into the US from another country, you may experience a more extensive screening process. We recommend arriving early at the airport to allow enough time for the screening process. Passengers must adhere to the TSA 3-1-1 rule for liquid limits. There have been recent changes in the UK regarding travel sizes (see below), but that applies only if flying within the United Kingdom.

Big things are happening in the UK regarding TSA rules

There finally might be an end to these regulations, or at least an improvement, starting in the United Kingdom . Rules about liquid limits and electronics through airport security are set to change. As of June 2024, most major UK airports will have new cutting-edge X-ray machines installed at their security checkpoints, welcoming a new era of improved security and happy passengers. These new machines will be able to detect larger, more detailed images, eliminating the need for passengers to remove their liquids and laptops, which will reduce long lines and, most importantly, detect potential threats. The 100ml liquid container limit will be extended to 2 liters (68 oz.) Currently, this only applies in the UK, so if traveling to the States, you must adhere to US TSA rules.

TSA liquid limits FAQs

• Why are there restrictions on taking liquids onto planes? In 2006, the TSA required strict liquid limits for carry-on luggage following a terrorist threat in which liquids were used to create explosives. The 3-1-1 Rules were designed as a safety precaution.
• What happens if you try to take more than 3.4 oz or 100ml of a liquid through airport security? If you pack oversized liquids (anything over 3.4 ounces or 100 ml), the TSA will most likely confiscate your items. Make sure to place larger items in your checked bags.
• Can you take empty bottles through security? Yes, empty bottles are a great way to save money and be sustainable. Most airports have refill water stations.
• Are there any full-size liquids you can take on planes? Yes, there are a few exceptions to the 3-1-1 Rule. Passengers can carry prescription medication, baby formula, baby teethers, and juice. If you're unsure if a specific item adheres to the 3-1-1 Rule, you can always contact the TSA.
• If I have TSA PreCheck, do I still need to follow the 3-1-1 Rule of liquid limits on the plane? Yes, TSA PreCheck still enforces the same standard limits. The only difference (and perk) is that passengers with PreCheck do not have to remove items from their bags.

Everything You Need to Know About TSA Liquid Rules

Get the details on flying with beauty products, medication, and other essential items.

Dealing with airport security can be a daunting aspect of air travel. There's a lot to contend with, from the long lines at checkpoints to keeping track of all the guidelines set by the Transportation Security Administration (TSA).

Travelers are frequently tripped up by the TSA liquid rules — specifically, the 3-1-1 policy regarding liquids in carry-on bags. From the detailed requirements for traveling with liquids to helpful packing tips, we explain everything you need to know before going through security.

What is TSA's 3-1-1 rule?

In 2006, British security officials thwarted a plot to bomb an aircraft with liquid explosives carried on board. Since then, security agencies around the world have limited the amount of liquid passengers can bring through airport security.

In the United States, TSA stipulates that all liquids, gels, and aerosols must be in 3.4-ounce (100-milliliter) containers or smaller. All liquids must fit into a single, clear quart-size bag, and passengers can only pack one of these bags in their carry-on.

The 3-1-1 designation is a simple way to remember these numbers: individual liquid containers must be 3.4 ounces or smaller, they must fit into one clear, quart-size bag, and there is only one bag allowed per passenger.

Permitted liquids that do not comply with the 3-1-1 rule must be packed in checked bags or thrown out at airport security. Some liquids, such as gasoline or other flammable liquids, are prohibited entirely, both in checked and carry-on bags.

Are there any exceptions to the 3-1-1 rule?

TSA does exempt some items from the 3-1-1 rule: medically necessary liquids, breast milk, infant formula, toddler drinks, and pureed baby food typically packaged in pouches. You can bring more than 3.4 ounces of these liquids on board, but you may have to undergo additional security screening.

"Inform the TSA officer at the beginning of the screening process that you're carrying them," TSA spokesperson Jessica Mayle tells Travel + Leisure . "These liquids are typically screened by X-ray, but TSA officers may also test them separately for explosives or concealed prohibited items. Officers may ask you to open the container and/or have you transfer a small quantity of the liquid to a separate empty container, or dispose of a small quantity, if feasible."

If you don't want your exempt liquids to be screened by X-ray, inform your TSA officer, and they will use alternative security measures to clear the items.

Another exception is liquids purchased after security in an airport. In domestic U.S. airports, you can bring nonalcoholic drinks and other liquid items purchased in terminal shops or eateries onto your flight. (This is not always the case if you are passing through security again in international airports for a connecting flight.) Duty-free liquids, however, will be sealed in a tamper-safe bag before boarding. Sometimes they're permitted in the cabin, and other times they may be stowed elsewhere on the plane.

You can also pass through security with liquids that have been frozen solid . By taking this extra step, you can easily tote your favorite drink past security — even if it's well over three ounces.

Rules about partially frozen items do not apply to some childcare items, such as ice or gel packs used to transport breast milk, formula, or baby food, or gel- or ice-filled baby teething toys. If these items are not completely frozen, they will be screened using the same procedures as medically necessary items. While hand sanitizer must conform to the 3-1-1 rule, wet wipes are allowed.

Packing Tips for Liquids in Carry-on Bags

• While many products are sold in 3.4-ounce sizes suitable for travel, not all of them are. Consider decanting your liquids into leakproof travel-size containers.
• "Another way to save space in your quart-sized bag is to pack solid versions of products, which you can put in your luggage or carry-on bag without needing to place it in the quart-size bag," travel advisor Ateet Ahuja of Complete Getaways tells T + L. "For example, you can bring a stick or solid version of some perfumes and shampoo bars instead of liquid shampoo." This solid Korean sunscreen stick is affordable and easy to pack.
• Buy your liquids, like body lotion or mouthwash, at your final destination. "While you'll spend a little extra, the cost far outweighs the potential of it spilling or leaking in your bag," says Ahuja.
• On that note, prepare for spills — Ahuja advises wrapping a small hand towel around your quart-size bag.
• Pack your liquids bag in an easy-to-access place, like an external compartment or the top of your carry-on bag. According to Ahuja, "This will save you time in the TSA line."
• Check the allowance for specific items using TSA's What Can I Bring? list . Here you'll find answers regarding everything from gel-style candles — not allowed — to dry ice, which requires airline approval rather than TSA approval.

If you're unsure about whether an item not listed adheres to the 3-1-1 rule, you can contact TSA before your trip. "Ask your questions via Facebook Messenger , weekdays from 8 a.m. to 6 p.m. ET," says Mayle. "You can also call the TSA Contact Center at 866-289-9673."

TSA Liquids Rule Explained: What Size Liquid Can You Bring on a Plane?

What you can and can’t bring on a plane, including the amount allowed, can be very confusing for even the most experienced of flyers, especially when it comes to liquids.

According to TSA regulations, you are allowed to bring liquids in containers that don’t exceed 3.4oz/100ml in your carry on.

There are also limits when liquids are packed in your checked bags, which many people are not aware of, though the limits are much greater.

What Size Liquid Can You Take on a Plane?

Carry on bags.

The TSA has a rule in place called the 3-1-1 Rule .

The 3-1-1 Rule states that “each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or 100 milliliters .”

These containers must also fit in a 1-quart sized, resealable bag.

You are required to take this bag out of your carry on and place it in a screening bin as you go through airport security.

Note that it is the size of the container itself and not how much liquid is in the container that matters.

So, if you have a bottle that contains just 1ml of liquid inside a 4oz container, it still won’t be allowed through.

Checked Bags

Not many passengers are aware that there are restrictions on the quantity of liquids you can pack in their checked bags.

According to the TSA:

• A container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
• The total aggregate quantity of your toiletry products must also not exceed 2 kg (70 ounces) or 2 L (68 fluid ounces).

No Differences For International Flights

Even though it may not be called the 3-1-1 rule worldwide, the rules remain the same if you’re flying internationally.

So regardless if you’re flying from or within Mexico, Canada, the UK, Europe or any other country, you are only allowed to pack liquids (as well as gels and aerosols) in containers that are no larger than 3.4oz/100ml in your carry on.

Airlines Follow TSA Regulations

All airlines follow TSA regulations .

So this means that regardless if you’re flying with Delta, Southwest, American Airlines, JetBlue, or any other regional or major air carrier worldwide, you are only allowed to bring liquids in containers that do not exceed 3.4oz/100ml in your carry on.

How to Pack Liquids for Flying

There are a few guidelines you should follow to make your next flight go as smoothly as possible.

• Make sure that no container you want to bring is no larger than 3.4oz/100ml.
• Buy travel-friendly products of your favorite products.
• If the company doesn’t sell travel-friendly sizes, buy your own 3.4oz/100ml containers and transfer the liquids into them.
• Consider packing non-liquid alternatives instead (you can bring a bar of soap on a plane on a plane , for example, with no restrictions. The same applies to sunscreen sticks ).
• Share toiletry space with your travel partner, as the 3-1-1 Rule applies to each passenger.
• Store your items in a clear bag that is no larger than 1 quart.
• Use your checked luggage for liquids in larger containers.

You Will Be Able to Bring 7-8 Bottles in Your Carry On

In total, you can take 32 ounces (or 1 quart) of liquids on a plane.

But as the containers themselves will take up space in the single quart-sized bag, you won’t be able to take a full 32 ounces of liquids in your carry on.

You will be able to bring about 25 ounces in total, in 7 or 8 travel-sized 3.4oz/100ml containers onto a plane in your carry on.

How Many Ounces in Total Can You Take On a Plane?

Carry on bags.

As just mentioned, you can bring 32 ounces (or 1 quart of liquids on a plane), though it will more likely be 25 ounces in 7-8 bottles.

If liquids are packed in your checked bags, each container must not exceed 18 ounces or 17 fluid ounces).

The total aggregate quantity of your toiletry products must also not exceed 70 ounces or 68 fluid ounces.

A Loophole to Bring More Than 3.4 Oz/100ml On a Plane

There is a loophole that lets you bring more than 3.4oz/100ml of liquids on a plane, though it only works with very few items and under certain circumstances.

If you are traveling with a young child or baby, you can say that the item is for them.

Of course, this will only work for bringing a water bottle on a plane and not items like alcohol, coffee or tea . 

Exceptions to the 3-1-1 Rule

There are several exceptions to the 3-1-1 Rule.

The following items, if packed in your carry on bags, are allowed to exceed 3.4 oz/100ml:

• Breast milk and formula
• Liquid medication
• Hand sanitizer
• Jumbo disinfecting wipes
• STEB items (secure, tamper-evident bags purchased at the airport)
• Cough syrup
• Gel-filled bras
• Saline solution
• Ice packs (must be frozen solid)

Liquids That Are Forbidden

There are several liquids that, even if under 3.4 oz/100ml, you are not allowed to bring on a plane in either your carry on or checked bags.

These items include:

• Most flammable liquids ( you can bring nail polish on a plane , though)
• Most toxic liquids
• Aerosols that do not qualify as toiletries
• Alcoholic Beverages over 70% ABV (140 proof)
• Insecticide
• Spray Paint
• Spray Starch
• Cooking Spray

Surprising Items That Qualify As Liquids

There are also items that you wouldn’t expect to count as liquids, but actually do.

• Peanut butter
• Hair mousse
• Snow globes

What the 3-1-1 Rule Stands For

The 3-1-1 Rule stands for 3 ounces, 1 passenger, 1 quart-sized bag.

While the limit is actually 3.4 ounces instead of 3 ounces, we guess that 3.4-1-1 Rule didn’t have the same ring to it.

Why the 3-1-1 Rule Exists

The 3-1-1 Rule exists because terrorists have previously tried to sneak liquid explosives on a plane on more than one occasion.

While the rule is frustrating, it exists for the safety of passengers.

Taking Liquids in Airplanes: How, How Much, and How to Do It

Travelpro Travel Expert Editor

Tips & Tricks

The TSA fluid limit for carry-on luggage exists for a reason. In 2006, Briain, the U.S., and Pakistan security foiled a plot by al-Qaeda operatives to set off bombs on airplanes using liquid explosives. The plan was to smuggle bomb materials onto planes using plastic drink bottles. Since then, the TSA has limited the amount of liquid passengers can bring onto planes to containers no larger than 3.4 ounces, a regulation commonly called the 3-1-1 rule.

The 3-3-1 Rule Simplified

The TSA’s fluid limit rule for carry-on liquids stipulates you can carry no more than 3.4 ounces per container of liquid. 3.4 ounces may seem like an odd amount, but it’s to keep TSA rules consistent with international regulations, which allow for 100 milliliters (3.4 ounces) per container.

The “3” in the 3-1-1 rule refers to the 3.4 ounce limit. All 3.4-ounce containers must fit into a clear one-quart bag: that’s the first “1.” Only one bag is allowed per passenger (that’s the last “1” in 3-1-1). Any liquids that don't meet these limitations cannot go through security and will be thrown away or confiscated.

The TSA and international airport security define substances most people consider to be solids or gasses as liquids, including aerosols, gels, creams, and pastes. Toothpaste, hair spray, peanut butter, shampoo, soup, mascara, and mouthwash are all considered liquids by the TSA. If you can squeeze, spray, or spread a substance, it falls under the 3-1-1 rule.

What are the Exceptions to the TSA Fluid Limit?

The TSA recognizes circumstances may require some passengers to carry more than 3.4 ounces of a liquid in their carry-on bags. Exceptions are made for items you would need during your flight or at your destination, if the items are unavailable at your destination and cannot be purchased after the security checkpoint. In practice, this usually means any of the following items:

• Baby and toddler drinks and food, including puree pouches
• Breast milk and infant formula
• Ice, gel, or freezer packs used to keep breast milk, infant formula, or medically necessary items cool
• Medical prescriptions that come in liquid, gel, or cream forms

Since 2020 passengers can travel with up to 12 ounces of hand sanitizer, an exception which may change in the future.

Travelers should alert TSA officers to any liquids that are exceptions to the 3-1-1 rule. All medication (liquid or otherwise) should be clearly labeled to help you move through security quickly. The TSA officer may visually check liquid exceptions, send the items through the X-ray machine, or test the liquid’s container for traces of explosives. You are responsible for displaying and repacking 3-1-1 exceptions, so keep any liquids and your  toiletry bag at the top of your carry-on for easy access. Remember that while prescription medication is exempt from the TSA fluid limit, non-prescription medications fall under the 3-1-1 rule.

X-ray screening machines do not affect infant or toddler food or drinks, but some travelers prefer not to take risks. Inform the TSA officer if you do not want food, drinks, formula, or breast milk x-rayed. Security will use other methods to clear the liquid, and you and your carry-on luggage will undergo additional screening. Be aware additional screening will slow your passage through security, so plan for the delay.

Are Frozen Liquids Liquid?

The TSA does not consider completely frozen liquids to be liquid, and therefore not subject to the 3-1-1 rule. The key phrase here is “completely frozen.” If the frozen substance is slushy or partially melted, it must meet the 3-1-1 requirements, regardless of the amount of thawed liquid in the container.

How many liquid ounces can be taken on a plane?

If you're wondering, “how many 3oz bottles can I carry on a plane,” the answer is approximately seven or eight. Any more, and you won’t be able to seal the bag with the containers inside. In terms of how many liquid ounces can be taken on a plane, this translates to approximately 25 liquid ounces.

The Quart-sized Bag, Explained

When it comes to quart-size bag dimensions, the TSA gives you some wiggle room. The average plastic resealable quart-sized bag is 7” by 8”. If you’re packing liquids in a travel toiletry bag, look for one which approximates these dimensions—people have had liquids confiscated for using bags TSA agents felt were too large, whether the bag was full of 3.4-ounce containers or not.

The TSA does not endorse any particular type of quart bag, so you can use anything from a travel toiletry bag to a Ziploc.

Liquids in Checked Luggage

Can you bring full-size bottles in a checked bag? The TSA has more lenient rules about liquids in  checked luggage . You can carry creams, gels, drinks, and toiletry-based aerosols in your checked baggage. 

RELATED: Consider the difference between hardside and softside Travelpro suitcases when thinking about packing liquids in your checked luggage.

The TSA prohibits certain liquids that pose a public danger from checked and carry-on luggage. Do not travel with any of the following:

• Alcoholic Beverages over 70% ABV
• Aerosols that are not toiletries
• Flammable liquids
• Toxic liquids
• Fertilizer 
• Insecticide

These liquids are prohibited in any amount, and their discovery during security checks can result in missed flights, arrest, and legal action.

Consider your destination when packing liquids in checked items. In many Islamic countries, for instance, alcohol is illegal or restricted and would be confiscated as you go through customs. Check the laws and regulations of your destination country before flying with liquids internationally.

What is the TSA 3-1-1 liquid rule?

Understanding the 3-1-1 liquids guidelines, tips for packing liquids in your carry-on luggage, the bottom line.

Whether you're flying to your destination or headed home, you might have non-solid items in your carry-on bag. Items can range from personal hygiene products — like shampoo or contact lens solution — to consumable souvenirs from your trip, like a mini bottle of rum from the Caribbean.

However, remember the Transportation Security Administration’s (TSA) 3-1-1 liquids rule when packing your carry-on luggage. This guideline states how liquids must be stored in the bag you take onboard, and enforces volume restrictions for liquid items.

Learn why it is called the 3-1-1 rule, and how to pack carry-on liquids effectively for a streamlined travel experience.

In September 2006, the TSA implemented the liquids restriction that travelers flying in and out of U.S. airports know today. The guideline is called the 3-1-1 liquids rule, which is meant to help passengers easily remember the rules for liquid in carry-on bags.

So, why is it called the 3-1-1 rule? Here’s what each number means:

3: Passengers can bring up to 3.4 ounces (“3” for simplicity) of liquid. This measurement also equates to 100 milliliters per container.

1: All liquid containers must fit into 1 quart-sized bag.

1: Only 1 quart-sized bag is allowed per passenger.

The TSA’s 3-1-1 rule applies to liquids, including gels, creams, pastes, aerosols, and consumable goods, like salsa, honey, and peanut butter.

Despite the easy-to-remember 3-1-1 liquids rule, there are a few details that some travelers might feel are open to interpretation. Here’s more clarification about the TSA’s guidelines.

The first thing to consider when bringing liquid in your carry-on bag is its container. According to the TSA, the size of the container is used to determine the amount of liquid.

For example, if you have a partially consumed sports beverage bottle that’s labeled 16 ounces, but only have 3 ounces of liquid left, this doesn’t follow the 3-1-1 rule. The container’s volume exceeds the allowable 3.4-ounce volume limit and isn't cleared to go through TSA checkpoint.

Additionally, all liquid containers must be put inside a clear, quart-sized resealable bag. Other bags, like clear, vinyl travel toiletry pouches with a zippered top, are also acceptable.

Finally, remove the liquids bag from your carry-on luggage when preparing your belongings for TSA checkpoint screening. They must be placed in a bin for review.

Does the 3-1-1 rule apply to TSA PreCheck?

If you have TSA PreCheck , a membership program operated by the TSA, you do not have to remove your liquids bag at screening, but its contents must still follow the 3-1-1 rule.

TSA PreCheck offers dedicated airport security lines and streamlined screening at a few hundred airports across the U.S. Membership lasts five years and costs $78-$85, depending on where you enroll.

However, you can join the program without paying out-of-pocket as it is an included benefit of many travel credit cards.

Although the 3-1-1 rule might feel restrictive, there are ways to pack liquid in your carry-on bag for the least hassle possible.

Ensure that containers are travel-sized.

Pack your liquids bag at the top, or front pocket, of your carry-on to easily separate it from your luggage at the checkpoint.

Consider purchasing travel-sized liquids (like toothpaste and shampoo) at your destination rather than packing them.

Consider using specially designed silicone travel bottle covers to add another layer of protection to your liquids. These can help prevent accidental spills in your bag.

Keep liquids more than 3.4 ounces in checked luggage.

When passing through a U.S. airport, you’ll need to ensure that your carry-on liquids follow the 3-1-1 rule. Each liquid container you bring must not exceed 3.4 ounces in size, and all containers must fit inside a single one-quart, clear and resealable bag.

By packing your carry-on with these guidelines in mind, you can breeze through TSA checkpoint lanes with fewer delays.

Liquid medication that exceeds the 3-1-1 rule can be brought through TSA lanes, including children's liquid medicine. The medication must be labeled as medication, and be separated from your carry-on luggage for screening. It will undergo a visual screening by a TSA agent or be passed through an X-ray screening. Additional screening techniques may be necessary.

Yes. Breast milk and baby formula are classified as medically necessary liquids, and are exempt from the 3.4-ounce volume limit. Breast milk and formula are not required to be stored in a one-quart clear, resealable bag. Other items necessary for safely cooling breast milk and formula, like ice packs, are also exempt. Breast milk, formula, and accessory cooling items require additional screening and must be removed from your carry-on bag for inspection.

The 3-1-1 rule doesn’t apply for duty-free liquids that are more than 3.4 ounces if it meets certain requirements. It must have been purchased either at a U.S. airport or purchased internationally if you have a connecting flight to the U.S.

You must have the original receipt that proves the liquid was purchased within the last 48 hours. Additionally, the retailer must secure the liquid in a transparent, sealed bag that hasn’t been tampered with.

Gel products, including any item that is spreadable out of the container, is subject to the 3-1-1 liquid rule. Gel items must be limited to 3.4 ounces or less per container, and containers must be stored in one clear, quart-size resealable bag.

Yes, the TSA cosmetics carry-on rules are the same as for other items, meaning the 3-1-1 rule applies to makeup. This includes all liquid, gel and semi-liquid makeup.

What is Considered Travel Size? TSA Liquid Limits and Travel Tips Explained

You can bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in your carry-on bag. Each container should not exceed 3.4 ounces (100 milliliters). This rule follows TSA regulations at checkpoints. Make sure all containers fit comfortably in the quart-sized bag.

Travel size is not only about liquids. It also includes creams, gels, and pastes that fit within the same size and bag requirements. Each passenger is allowed one bag, which should be easily accessible during security screening. Liquid medications and baby items follow different regulations and are often exempt from these limits, but they still need to be declared at security.

When packing your travel size essentials, consider how often you use each item. Opt for multi-purpose products to save space. Always measure your liquids in advance to ensure compliance. Being prepared can make the travel experience smoother.

Next, we will explore the best practices for selecting travel size items and tips on how to maximize your packing efficiency. This information will help you maintain convenience without sacrificing essential products during your journey.

What is Considered Travel Size in Terms of Liquids?

Travel size for liquids is defined as personal care items and liquids that do not exceed 3.4 ounces (100 milliliters) per container. This regulation applies to air travel, where passengers are restricted to carry-on bags.

The Transportation Security Administration (TSA) outlines these rules on their official website, indicating that all liquids must be within the 3.4-ounce limit to pass through security checkpoints.

Travel size liquid regulations ensure that airline travel remains safe. This limit is part of security protocols that prevent potentially hazardous materials from being brought onto aircraft. Each passenger can carry multiple containers, provided they fit within a single quart-sized clear plastic bag.

The Federal Aviation Administration (FAA) also supports this guideline, emphasizing that compliance helps facilitate faster screening processes. Each bag should be easily accessible for security personnel during inspections.

Several factors contribute to these regulations, including global security threats and the need for efficient airport screening systems. Compliance reduces the risk of dangerous materials being smuggled onto flights.

According to the TSA, over 99% of travelers successfully comply with these liquid regulations each year. However, non-compliance can lead to delays and prohibited items being discarded.

These regulations impact passenger convenience and airport efficiency. Understanding travel size limits can reduce frustration at security lines and enhance the overall travel experience.

In a broader context, liquid size regulations contribute to public safety. They help maintain levels of security required in air travel without imposing excessive burdens on travelers.

To navigate these rules effectively, travelers should use pre-approved containers and always check their airline’s regulations. Pre-planning can minimize security hassles and ensure smooth travel experiences.

Strategies include using travel-sized containers, adhering to airport guidelines, and packing efficiently. Several companies also manufacture travel-friendly products specifically meeting these requirements.

What are the TSA Liquid Limits for Carry-On Luggage?

The TSA liquid limits for carry-on luggage allow travelers to bring liquids in small containers, with specific restrictions on the total volume and type of liquid.

• Container size limit: Each container must hold 3.4 ounces (100 milliliters) or less.
• Bag size limit: All containers must fit within a single quart-sized, clear plastic bag.
• Total number of bags: Travelers can carry one quart-sized bag of liquids.
• Exceptions: Certain items such as medications, infant food, and breast milk may exceed the limits.
• Screening process: Liquids must be presented separately during security screening.

Understanding the TSA liquid limits is important for smooth airport travel.

Container size limit: The TSA liquid limit states that each container of liquid must be 3.4 ounces (100 milliliters) or less. This restriction helps ensure that liquids do not pose security risks within the cabin of an airplane. For example, if a passenger attempts to carry a standard 16-ounce bottle of shampoo, it will be confiscated at security.

Bag size limit: The TSA mandates that all liquid containers must fit within a single quart-sized, clear plastic bag. This rule is designed for efficient screening. The bag helps TSA officers easily identify liquids and streamlines the security procedure.

Total number of bags: Travelers are allowed one quart-sized bag of liquids in their carry-on. This limitation ensures that the number of liquid items remains manageable during transportation. Carrying more than one bag can lead to delays at the security checkpoint.

Exceptions: The TSA provides exceptions for certain liquids like prescription medications, infant formula, and breast milk. Passengers can carry these items in larger quantities, but they must inform security officers. This flexibility accommodates travelers who may require specific liquids for health or childcare purposes.

Screening process: During security screening, liquids must be removed from carry-on bags and placed in a separate bin. This requirement allows TSA agents to inspect the liquids quickly and efficiently. Travelers who do not adhere to this rule may experience longer wait times.

Travelers should familiarize themselves with these limits to avoid complications at security checkpoints.

How Many Ounces of Liquid are Allowed in a Carry-On?

Travelers are allowed to bring liquids in containers of 3.4 ounces (100 milliliters) or less in their carry-on luggage. This rule applies to all liquids, gels, creams, pastes, and similar substances. The Transportation Security Administration (TSA) enforces this regulation as part of broader security measures to ensure safe air travel.

Each passenger can bring a quart-sized, clear, resealable plastic bag containing these containers. This allows for a total volume of approximately 34 ounces (1 liter) of liquid. Liquids exceeding this limit must be packed in checked baggage. Exceptions exist for certain items, such as medications, baby formula, and breast milk, which can exceed the 3.4-ounce limit but must be declared during screening.

For example, a traveler might pack a small bottle of shampoo, some lotion, and a travel-sized mouthwash, all within the 3.4-ounce limit, inside a quart-sized bag. If a passenger has a larger container of liquid, they could either transfer a portion into a smaller bottle or choose to check the larger item.

Factors influencing these limits include airport security protocols and variations in international travel rules. Some countries have different regulations regarding liquid restrictions. Additionally, travelers should consider that delays in security checks can also occur if liquids are not properly contained, emphasizing the importance of compliance with size regulations.

In summary, travelers can carry liquids in containers of no more than 3.4 ounces, with a total volume restriction of 34 ounces in a resealable bag. Exceptions apply to certain items such as medications. Adhering to these guidelines will facilitate smoother airport security experiences. Further exploration could include varying international regulations or tips for efficiently packing liquids for travel.

Airports often have shops selling travel-sized toiletries, allowing you to bypass the limitations altogether. According to a report by the Airports Council International (ACI), many travelers find this option beneficial for convenience and efficiency during travel.

Use multi-functional products : Using multi-functional products helps save space. For example, a combined shampoo and conditioner or a moisturizer with SPF reduces the number of items you need to bring. Beauty experts suggest that products serving multiple purposes can streamline your travel routine and lower the amount of liquids packed.

Pack efficiently : Packing efficiently includes organizing your items and removing non-essential products. Prioritize essentials and carefully consider what you truly need based on the duration of your trip. A surveyed group of frequent travelers reported that packing cubes improved their organization, making it easier to adhere to size restrictions.

By following these tips, you can navigate travel size restrictions smoothly while ensuring a comfortable travel experience.

How Can You Efficiently Pack Travel Size Toiletries?

To efficiently pack travel-sized toiletries, prioritize using containers that meet size regulations, choose multi-purpose products, and secure items to prevent leakage.

When packing travel-sized toiletries, consider the following strategies:

Adhere to TSA Regulations : The Transportation Security Administration (TSA) has specific rules regarding liquid items. Travelers can bring liquids in containers of 3.4 ounces (100 milliliters) or smaller. All containers must fit within a quart-sized (approximately one liter) clear plastic bag. This regulation ensures you remain compliant and avoids delays during security checks.

Opt for Multi-Purpose Products : Selecting products that serve multiple functions can minimize the number of items packed. For example: – A combined shampoo and conditioner reduces the need for separate bottles. – A moisturizer with SPF can serve as both skincare and sun protection, which saves space.

Utilize Refillable Travel Bottles : Consider using refillable bottles specifically designed for travel. These bottles often come in 3.4-ounce sizes and are made of flexible materials, which makes them easy to squeeze and dispense liquids. Using such containers allows you to carry your preferred products while ensuring compliance with TSA rules.

Secure Containers to Prevent Leakage : To avoid leaks during travel, make sure to: – Cap all bottles tightly and seal plastic bags with zip closures. – Place tape over the openings of bottles or containers for extra security. – Use packaging such as mesh pouches to keep toiletries organized and limit movement within your bag.

Organize Toiletries for Easy Access : Grouping your toiletries into categories (like skincare, hair care, and oral hygiene) can help you find items quickly. Consider packing items in a clear cosmetic bag to view contents easily and keep everything in one place.

Implementing these strategies can streamline your packing process and ensure a more enjoyable travel experience.

What are Some Creative Alternatives to Travel Size Products?

Creative alternatives to travel size products include using refillable containers, multi-use products, solid variants, homemade solutions, and sample-sized items.

• Refillable containers
• Multi-use products
• Solid variants
• Homemade solutions
• Sample-sized items

These alternatives provide diverse perspectives on how to minimize packaging while still meeting personal care and convenience needs.

Refillable Containers: Refillable containers are empty bottles or jars designed to be filled with products like shampoos, lotions, or creams. These containers can be reused multiple times, reducing waste and saving space in luggage. According to a 2021 study by the Ellen MacArthur Foundation, switching to refillable systems can significantly cut down single-use plastic consumption. Many companies, such as Muji and Lush, sell refillable containers, allowing consumers to enjoy their favorite products without environmental guilt.

Multi-use Products: Multi-use products serve more than one function, such as a moisturizer that also acts as a sunscreen or a lip and cheek tint. By combining multiple uses into a single item, travelers can save space and reduce the number of products they carry. A survey reported by the Consumer Product Testing Company in 2022 found that 70% of consumers prefer products that offer versatility. For example, coconut oil can be used for skin care, cooking, and hair conditioning.

Solid Variants: Solid variants of liquid products, like shampoo bars and conditioner bars, are effective and eco-friendly substitutes. They often contain less water and can be packaged with minimal plastic, thereby reducing waste. According to a 2020 article by EcoWatch, switching to solid products can reduce plastic waste by up to 80%. Popular brands like Ethique and Friendly Soap offer these alternatives, appealing to eco-conscious travelers.

Homemade Solutions: Homemade solutions involve creating personal care products from easily accessible ingredients, such as olive oil, vinegar, or essential oils. This method allows individuals to customize their products according to preferences, ensuring purity and safety. A 2019 study in the Journal of Environmental Psychology highlighted that DIY products can foster a greater sense of environmental responsibility. For instance, a simple mix of sugar and olive oil can serve as an effective exfoliant.

Sample-sized Items: Sample-sized items are small versions of beauty or care products often available for free at retailers or as part of promotions. These sizes are convenient for travel and often allow consumers to try new products without committing to full-size purchases. The 2022 Beauty Industry Report noted that the demand for sample sizes increased by 25% as travelers seek convenience and variety while on the go. Brands like Sephora and Ulta regularly offer these samples, encouraging consumers to explore new options.

What Should You Know About International Travel Size Guidelines?

The primary aspect to know about international travel size guidelines is that they regulate the dimensions and weight of luggage and carry-on items, as well as the restrictions on liquids and gels. Each airline may have specific policies, so it’s important to verify these guidelines based on your airline and destination.

• Carry-On Luggage Size : Most airlines allow a standard dimension.
• Checked Luggage Size and Weight Limits : Varies by airline and class of travel.
• Liquid Restrictions : TSA guidelines limit liquids in carry-on bags.
• Special Items : Considerations for sports equipment or musical instruments.
• Regional Differences : Variations in size and weight guidelines globally.
• Excess Baggage Fees : Costs associated with exceeding size or weight limits.

Understanding these types is essential to avoid complications during your journey. The following paragraphs provide a detailed explanation of each point.

Carry-On Luggage Size : International travel size guidelines specify that carry-on luggage should generally be no larger than 22 x 14 x 9 inches (56 x 36 x 23 cm) for most airlines. This dimension allows the bag to fit in the overhead compartment or under the seat. For example, Delta Airlines and American Airlines maintain similar limits, while Ryanair and Southwest may have smaller dimensions.

Checked Luggage Size and Weight Limits : Each airline establishes its own size and weight restrictions for checked bags. Commonly, the weight limit is about 50 pounds (23 kg) for economy class travelers. Lufthansa, for instance, allows up to 70 pounds (32 kg) for business class. It’s important to check the specific guidelines of your airline to avoid excess baggage fees.

Liquid Restrictions : Transport Security Administration (TSA) guidelines restrict fluids in carry-on luggage to containers of 3.4 ounces (100 milliliters) or less. These containers must fit in a single quart-sized clear zip-top bag. This applies to all fluids, gels, and aerosols. Variations exist internationally, but many countries follow similar restrictions outlined by the TSA.

Special Items : Certain items like sports equipment or musical instruments may have unique size and handling requirements. Airlines might transport these as checked luggage or allow them as additional carry-ons. Checking with the airline ensures carefree travel with special items.

Regional Differences : International travel guidelines can vary significantly across airlines and countries. For instance, Asian airlines often have stricter weight limits, while some low-cost carriers in Europe enforce tighter baggage dimensions. Knowledge of these differences can save travelers from potential issues.

Excess Baggage Fees : Exceeding luggage size or weight limits typically incurs additional fees. These fees can range from $50 to over $200, depending on the airline and the extent of the excess. Planning and weighing your luggage before flying can help avoid inflated costs.

Verifying these guidelines helps ensure a smooth travel experience while keeping you informed about the potential variations across different airlines and destinations.

How Do International Travel Size Regulations Differ from TSA Rules?

International travel size regulations often vary from TSA rules, mainly in terms of liquid restrictions and the dimensions of carry-on baggage. While TSA rules apply specifically to airports in the United States, international regulations may differ by country and airline.

International liquid restrictions: Many countries have similar liquid restrictions to TSA but may allow different quantities or types of containers. For example, TSA restricts liquids to containers of 3.4 ounces (100 milliliters) or less, while some countries may allow larger containers in checked baggage but maintain the same limit for carry-ons.

Container requirements: TSA requires liquids to be placed in a quart-sized bag for carry-on luggage. In contrast, some international airports allow liquids to be packaged differently, depending on their local guidelines.

Additional allowances: Certain international airlines may permit additional items not allowed by the TSA. For instance, duty-free purchases may be carried in larger quantities, as long as they remain sealed in the provided security bag.

Check airline policies: Airlines often outline specific requirements for carry-on size, weight, and permitted items. Travelers must verify regulations for the specific airline they plan to use, as these may differ from TSA rules.

Local variations: Different countries may have unique security measures. Some nations may not require the same security screenings or may have different rules regarding items like electronics or personal care products.

Understanding these aspects helps travelers navigate the complexities of flying internationally while adhering to varied regulations efficiently. It is advisable to familiarize oneself with both TSA rules and the specific regulations of the countries to be visited.

What Common Mistakes do Travelers Make Regarding Travel Size?

Travelers often make several common mistakes regarding travel size, particularly concerning liquid and baggage regulations.

• Exceeding TSA liquid limits
• Misunderstanding travel size definitions
• Neglecting bag size regulations
• Ignoring packaging requirements
• Overpacking essentials

To avoid these pitfalls, it is essential to understand the specific rules and guidelines for travel size items and baggage.

Exceeding TSA Liquid Limits : Travelers frequently exceed TSA liquid limits of 3.4 ounces (100 milliliters) per container. This regulation, outlined by the Transportation Security Administration (TSA), states that all liquids, gels, and aerosols must fit within a quart-sized bag. Failure to comply results in longer security checks or item disposal, which can lead to frustration.

Misunderstanding Travel Size Definitions : Travel size definitions can confuse many travelers. Various airlines define travel size differently, often considering items under 3.4 ounces as suitable. However, some customers mistakenly assume any item labeled “travel size” is acceptable. Consequently, they may face delays or additional fees at check-in if their carry-on bags are over the prescribed limits.

Neglecting Bag Size Regulations : Many travelers neglect to check their airline’s specific bag size regulations. Most airlines have unique criteria regarding dimensions for carry-on and personal bags. Common mistakes include using oversized bags, which could lead to additional fees or the necessity to check the bag unexpectedly.

Ignoring Packaging Requirements : Travelers often overlook the necessity of complying with packaging requirements. It is essential that liquids and gels be in containers that are leak-proof and clearly labeled. Ignoring this can result in spills that damage clothing or other items, leading to a chaotic travel experience.

Overpacking Essentials : When packing their bags, travelers tend to overpack essential items by including unnecessary items that do not fit travel size guidelines. This not only results in larger bags but also increases the risk of lost or damaged items during transit.

Understanding these common mistakes can help travelers better prepare for their journeys and encourage a smoother travel experience.

How Can You Avoid Overpacking Travel Size Items?

You can avoid overpacking travel-size items by planning ahead, selecting multipurpose products, and adhering to guidelines for liquid limits.

Planning ahead involves creating a list of essential items before packing. This prevents last-minute additions of unnecessary products. Assess your daily needs, such as skincare, hair care, and hygiene, to include only the must-haves. According to a study from the Journal of Travel Research (Smith, 2021), travelers who plan their packing typically bring fewer items and enjoy a more organized experience.

Selecting multipurpose products can significantly reduce the number of items you carry. Look for shampoos that double as body wash or lotions that can serve as both moisturizer and sunscreen. A report in the International Journal of Consumer Studies (Johnson, 2020) indicated that multifunctional items are not only economical but also efficient for packing.

Adhering to liquid limits for carry-on luggage is vital to avoid overpacking. The Transportation Security Administration (TSA) regulations state that each liquid container must be 3.4 ounces (100 milliliters) or less, and all must fit into a one-quart clear, resealable bag. Understanding these regulations helps prevent bringing excessive liquids.

By implementing these strategies—planning, choosing multipurpose products, and following liquid limits—you can ensure you travel light with only necessary items.

What Is Not Allowed in a Plane Carry-On Bag, From Magic 8 Balls to Baseball Bats

What is not allowed in a plane carry-on can sometimes be unclear for many travelers—especially in light of the recent back-and-forth on the 100ml liquid limit in the UK and EU.

Packing everything you need for a trip into one bag and surviving the throes of airport security is stressful enough. The last thing any traveler wants is to be stopped by TSA and have your belongings rummaged through. So, when it comes to preparing for a flight, whether international or domestic —tactful and organized packing is only ideal for future-you.

When packing your carry-on luggage with all your travel essentials , it’s important to check what’s legally permitted—and not permitted—to carry on a plane. To make things easier, we’ve compiled a reference list based on the TSA’s Security Screening guidelines .

What are the liquid requirements for carry-on bags?

In the US, the TSA enforces a 3-1-1 rule , which means you can only pack liquids into containers smaller than 3.4 ounces that fit all together in one clear quart-sized bag. This is consistent with the international 100ml liquid limit (3.4 ounces is equal to 100 milliliters).

As bag screening technology evolves from 2D X-ray scanners to more advanced CT scanners, the hope is that the 100ml liquid limit will eventually be scrapped—but with airports around the world facing very different timelines for installing the new machines, the rule likely won’t go away anytime soon .

So, exactly which products have to be packed according to the 3-1-1 rule? Most of our personal care items are liquids (shampoo, perfume or cologne, contact lens solution, nail polish), gels (toothpaste, face serums, hair gels), aerosols (in a pressurized spray bottle or can, such as hairspray or spray-on deodorant), creams (lotions), and pastes (toothpaste). When packing any of the above into your carry on, first make sure they are non flammable. Then, check their size as marked on the container label and zip them into your TSA-approved toiletry kit .

Remember, TSA liquid restrictions fall specifically on the container itself, not its contents—so even if your face wash has less than 3.4 oz of liquid left inside, it doesn’t matter if the container is larger than allowed. These requirements also pertain to e-liquids for vaping devices and electronic cigarettes, as well as canned jars of food , like salsa, peanut butter, and cream cheese—and to alcohol (mini bottles are permitted as long as the alcohol content is less than 70%).

Of course, there are a few exceptions. For example, baby formula and baby food are not required to meet the 3-1-1 rule—but they must be declared for screening and removed from your carry-on luggage at the security checkpoint. For a list of full-size liquids you can actually take through airport security, see our complete guide .

Some surprising items that are not allowed in carry-on luggage because they typically contain more liquid than permitted include large snow globes and Magic 8 Balls. And yes, even the no-nonsense TSA can admit this is funny: “For Carry-on bags: We asked the Magic 8 Ball and it told us…Outlook not so good!” the agency jokes on its website . “For Checked bags: We asked the Magic 8 Ball and it told us…It is certain!”

What other items are not allowed in carry-on bags?

Packing a pair of scissors, perhaps to cut off new clothing tags or give yourself a mid-trip haircut, is an innocent mistake that can easily derail your travel plans. Only small scissors with blades at a maximum of four inches from its pivot point are permitted in carry-on luggage. Other smaller tools including screwdrivers, pliers, nail clippers, and bottle openers must all be under seven inches long. Any sharper tools (like box cutters) must be securely sheathed or wrapped in checked baggage.

Athletic equipment such as ski or hiking poles, hockey sticks, baseball bats, and tent spikes are not allowed in carry-on bags and must be transported in checked luggage. Check with your airline if you're traveling with sports gear like bicycles, longboards, fishing poles, tennis rackets, or snowshoes, as the policies can vary (and some carriers will charge additional fees).

Travelers cannot pack the majority of standard self-defense items in carry-on bags. However, pepper spray can be packed in checked luggage at a maximum weight of 4 ounces—and with a safety mechanism to prevent accidental discharge. Other weapons like Swiss Army knives , black jacks , and kubatons (a self-defense keychain tool) can only be packed in checked luggage, not carry-on bags.

When traveling for an event—say a destination wedding —you may find yourself traveling with a wrapped present. And though the thought is nice—and wrapped gifts can, in fact, be carried on board—the interior contents still must meet security standards. Solid wax candles, which make for a nice packable gift, are permitted in carry-on bags, but gel-like candles can only be transported in checked luggage. Note: security screeners often unwrap gifts for inspection, so it might be a safe bet to leave all gifts unwrapped until your arrival.

What medications can be packed in a carry-on bag?

Medications in pills or other solid forms can remain in your carry-on. The TSA does not require that they be packed in a labeled prescription bottle, but it can help facilitate the security screening process. Liquid medications are another story.

“TSA allows larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your flight, but you must declare them to TSA officers at the checkpoint for inspection,” the agency explains on its website . “Remove medically necessary items from your carry-on bag, and place them in a bin or bowl. If a medically necessary liquid, gel, or aerosol alarms additional screening will be required. If the alarm cannot be resolved, the item may not be allowed.”

Leave these items at home

Some prohibited items are not allowed in neither carry-on nor checked luggage. You will need to leave these at home, or risk facing penalty charges . Attempting to carry on flammable materials or certain weapons can result in fines of up to several thousand dollars.

This may or may not go without saying, but all flammable materials (aerosol cans over 3.4 ounces that hold fuels, gasoline, butane, lighter fluid, certain paints , gas torches, etc.) cannot be flown with on any commercial flight. These restrictions strictly apply explosive materials, chemicals (spray paint, fertilizers, bleach, etc.), wildlife safety items (like bear spray) and alcoholic beverages over 140 proof (such as grain alcohol and 151-proof rum).

Rules for Liquids in Checked Baggage: The Complete Guide

DIY Ways to Secure Your Packed Liquids

Go with the pros, add padding, anticipate inspections, tips for packing liquids in checked baggage.

TripSavvy / Ashley DeLeon 

You can carry liquids in checked baggage, but you will have to do some research and take precautions. First, you must find out which liquids are not allowed on airplanes regardless of where you pack them. The Transportation Security Administration (TSA) has a list of these prohibited liquids on its website . You should also look at the Federal Aviation Administration's list of hazardous materials. Never try to bring prohibited materials with you when you fly.

After you've done your research, you must determine whether you can bring the liquid items of your choosing to your destination. If you plan to carry several bottles of wine, for instance, you may not be able to bring them into certain U.S. states due to liquor import regulations. Travelers flying to or from Canada will want to read the Canadian air travel regulations, and visitors to the UK should read the United Kingdom's list of items you may carry in hand (carry-on) and hold (checked) baggage.

Your next step is to decide whether you want to pack colored liquids, such as red wine or nail polish, which could damage your clothing. Carrying any colored liquid can be risky. Decision-making factors include whether these items are available at your destination and whether your itinerary is flexible enough to allow you to purchase them locally, rather than bring those liquids with you.

Finally, you will need to carefully pack your liquid items so they will not break or leak. There are several ways to accomplish this. Read on for our complete guide on what to know before packing liquids for your next trip.

To prevent leaks, wrap the top of your bottle or container with duct tape so the cap stays on. (You may also want to pack a small pair of sharp scissors in your checked bag so you will be able to remove the tape later.) Put the container into a zipper-top plastic bag and seal the bag closed. Next, place that bag into a larger zipper-top bag and seal it closed, pressing out all the air as you do so. Wrap the whole thing in bubble wrap if the container is breakable. Finally, wrap that bundle in a towel or in clothing. (Many travelers suggest using dirty laundry for this.) Place the wrapped bottle or container in the middle of your largest suitcase, surrounded by clothing and other soft items.

A variation on this method involves using a hard-sided plastic or cardboard container to protect your liquid item. Use a small cardboard box or a sealed plastic container. Double-bag the liquid item as described above. Then, place it in the container and pad it with crushed newspapers, plastic air pillows or crumpled plastic grocery bags. Tape the box shut and pack it in the center of your suitcase.

You can buy styrofoam or bubble wrap "shippers," which are sealable padded bags. Brand names include the inflatable VinniBag or the Wine Mummy. Boxes made especially for transporting glass and liquid items are another option. Your local wine shop or pack-and-wrap store may carry shippers. Be aware that the bubble wrap bags will keep escaping liquid from staining your clothes, but may not prevent glass bottles from breaking. The box shipper will take up more room in your luggage. While it may not prevent liquid from escaping, the box shipper minimizes the risk of breakage.

Protect your liquid items by placing them in the middle of your suitcase, completely surrounded by clothing and other items. Be aware that your suitcase could be dropped or crushed, perhaps more than once, on its way to your destination. It may even be dragged on the ground behind a luggage cart. If you can choose from several suitcases, pick the one with the stiffest sides and pack it as tightly as you can to better cushion your liquid items.

If you pack liquid items in your checked bag, assume that your bag will be inspected by a baggage security screener. The screening officer will see your liquid item on the baggage scanner and will probably need to take a closer look at it. Do not pack valuables, even liquid ones, or prescription drugs in your checked baggage.

• Careful packing and padding will increase your chances of success, so make sure to transfer all liquids to leak-proof containers.
• Pare down your packing. Not everything can fit in your suitcase! Decide what toiletries you may find up for grabs in your hotel room, and edit, edit, edit.
• Two-in-one items are always a good idea.
• If you have a large-sized soap or shampoo that you really want to take on your trip, invest in travel-sized toiletry bottles . This way, you can pour some into the correctly sized bottle and still be allowed to take it with you on your trip.
