The Transportation Security Administration (TSA) has specific requirements for carry-on bags at airports. The 3-1-1 rule, introduced in 2006, states that all liquids, gels, and aerosols must be in 3.4-ounce containers and fit into a single, clear quart-size bag. This bag should be placed separately from your carry-on baggage to facilitate the screening process. While TSA does not specify that the bag must be clear, using a clear bag allows TSA agents to easily see the contents and expedite the process. These bags are typically around 6 by 9 inches or 20 by 20 centimeters in size and can be purchased online.

Clear bags for airport security are typically 20x20cm or 6x9 inches
The 20x20cm bags are often made of robust, waterproof, and leakproof material, such as vinyl, and have secure seals and closures to prevent leaks. They are designed to meet the requirements of various airport security authorities, including the TSA, EU, and CAA. These bags are ideal for carrying travel-sized liquids and have features like wrist straps for convenience.
The 6x9-inch bags are also TSA-approved and can be used for carrying liquids, makeup, and toiletries. These bags are often made of clear, eco-friendly plastic or vinyl and may have features like zip closures.
It is important to note that while clear bags are commonly used for carrying liquids, some airport security regulations, like the TSA, do not explicitly require the bag to be clear. However, using a clear bag can expedite the screening process as agents can easily inspect the contents without further inspection.

The 3-1-1 rule: liquids must be 3.4oz, in 1 bag, 1 bag per person
The 3-1-1 rule is an essential part of preparing for a smooth, hassle-free security check at the airport. Introduced in 2006 after British officials stopped a plot to detonate liquid explosives on board international flights headed to the U.S., the rule simplifies the process of packing liquids for air travel.
The first '3' in the 3-1-1 rule stands for 3.4 ounces, or 100 milliliters. This is the maximum size each liquid container can be. It's important to note that this rule applies to most liquids, but there are some exceptions, such as medications and baby formula, which are exempt from the 3-1-1 rule.
The '1' refers to the one quart-sized, transparent, resealable bag that these containers must fit into. It is recommended to use clear, zippered pouches and to pack your TSA liquids bag at home. This allows security officers to easily see the contents of the bag and ensure they comply with the rule.
The final '1' indicates that each passenger can carry only one such bag. This means that each person is limited to carrying as much liquid as can fit inside 3.4-ounce containers that fit inside one plastic quart-sized bag. However, you can bring larger containers of liquids in your checked luggage.

Liquids include gels, creams, pastes, and aerosols
Liquids, gels, creams, pastes, and aerosols are subject to strict regulations at airport security. These restrictions were introduced in 2006 after British officials foiled a plot to detonate liquid explosives on board international flights headed to the US.
Any liquids, gels, creams, pastes, or aerosols must be in containers no larger than 3.4 fluid ounces (or 100 milliliters) to be allowed through security in your carry-on luggage. This includes items such as toothpaste, hair gel, shower gel, shaving foam, hairspray, spray deodorant, creams, lotions, oils, perfumes, mascara, lip gloss, contact lens solution, and other similar items. These items must be placed in a clear, quart-sized bag, and only one bag per passenger is allowed. The bag must be separate from your carry-on luggage to facilitate the screening process.
Any liquid, gel, cream, paste, or aerosol that is over the allowed limit of 3.4 ounces or 100 milliliters should be packed in your checked baggage. This includes full-size shampoo, face wash, and other non-essential liquid toiletries. It is recommended to use solid alternatives, such as shampoo bars, sunscreen sticks, solid perfumes, and toothpaste tablets, to maximize space in your quart-sized bag and avoid waste.
Duty-free liquids purchased internationally and transported in a secure, tamper-evident bag may be allowed in quantities exceeding 3.4 ounces or 100 milliliters in your carry-on bag when travelling to the United States with a connecting flight. However, these items must be packed in a transparent, secure, tamper-evident bag by the retailer and show no signs of tampering when presented for TSA screening.

Medication is exempt from the 3-1-1 rule but must be clearly labelled
For air travel, you are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in your carry-on luggage. These items must be in travel-sized containers that are 3.4 ounces (100 milliliters) or less per item. This is known as the 3-1-1 rule: 3.4 ounces, in one quart-sized bag, for one person.
Medication is exempt from the 3-1-1 rule, but it must be clearly labelled. This means that you can bring larger containers of medication in your carry-on luggage, as long as they are clearly labelled and prescribed to you. It is important to note that medication in liquid or gel form that is not prescribed to you, such as cough syrup or gel capsules, must adhere to the 3-1-1 rule.
Additionally, any medication that is a controlled substance listed in Schedule II, III, IV, or V of the Federal Controlled Substances Act must be dispensed by prescription only. This means that you should have a prescription with you when travelling with these medications.
To make the airport screening process as smooth as possible, it is recommended to use clear, zippered pouches for your liquids and medications and to pack them separately in an easily accessible outer pocket of your carry-on luggage. This allows for easy access during screening and facilitates the process.
It is also important to note that any liquid, aerosol, gel, cream, or paste that alarms during screening will require additional screening. These items should be packed in a way that is easily accessible and separate from your other belongings.

Solid alternatives to liquids can be used to save space
For air travel, the Transportation Security Administration (TSA) requires that all liquids, gels, and aerosols in carry-on bags be in containers of 3.4 fluid ounces (100 milliliters) or smaller. These containers must fit into a single, clear quart-size bag, and only one bag is allowed per passenger. This is known as the 3-1-1 rule.
To save space, you can use solid alternatives to liquids. Solid substitutes are often as good as, if not better than, their liquid counterparts. They can help to streamline your travel routine, especially for long-haul trips where small bottles of liquid may not be sufficient. Solid alternatives also reduce the risk of spills.
- Shampoo and conditioner bars: Lush makes a solid shampoo in the shape of a hockey puck, and Chagrin Valley Soaps offers a shampoo bar as well. You can also use conditioner bars, such as Lush Jungle, which can also be used for shaving.
- Solid deodorant: Crystal deodorant sticks are available in a tiny travel size.
- Solid lotion: Lotion bars are available from many suppliers, including the Bee Bar from Honey House, which contains higher amounts of beeswax so it's less likely to melt. Massage bars can also be used as a solid lotion substitute, but they may melt in warm weather.
- Solid mouthwash: You can dissolve 1/2 teaspoon of salt into 1/2 cup of water for a mouth rinse and store the salt in a small container.
- Solid toothpaste: Toothpaste tablets, such as Bite Toothpaste Tablets, or toothpaste powder, such as Pretty Frank Toothpaste Powder, can be used instead of traditional toothpaste.
- Solid sunscreen: Sunscreen is available in TSA-friendly balms and powders, which may be more convenient than liquid sunscreen.
- Solid perfume: Solid perfumes can be a great alternative to liquid perfumes and can help you save space.
