Crystallization – This is the type you bend or tap to activate. They contain liquid and must comply with TSA 3-1-1 fluid guidelines. They can be packed in hand luggage and checked in. The 3-1-1 rule means you can take liquids, gels and aerosols — think items like toothpaste, shampoo, conditioner, mouthwash and lotion — in travel containers on an airplane. The caveat is that each container can only hold 3.4 ounces (100 milliliters) or less. And the products must fit in a one-liter resealable bag. As long as these small items fit in the bag, you can take them beyond safety. One rule travelers often stumble upon is the Transportation Security Administration`s (TSA) 3-1-1 regarding liquids in carry-on baggage. We`re here to walk you through the details of the rule and provide helpful tips for packing liquids when flying. You may carry duty-free liquids in secure, tamper-evident bags over 3.4 oz or 100 ml in your carry-on bag if: If your liquids are stored in containers larger than 3.4 ounces, even if only 3.4 ounces remain in the bottle, you will not be able to get them through security. You must put them in your checked baggage. However, you can bring a reusable water bottle as long as it is empty when you pass the TSA checkpoint. “Inform the TSA agent at the beginning of the screening process that you are wearing them,” Mayle says.

“These liquids are usually examined by X-ray, but TSA agents can also test them separately for explosives or hidden contraband. Officers may ask you to open the container and/or pour a small amount of the liquid into a separate empty container or dispose of a small amount if possible. For the TSA, which regulates travel to the United States, all liquids, gels and aerosols must be in containers of 3.4 ounces (100 milliliters) or less. All liquids must fit in a single, pint-sized transparent bag – passengers can only pack one of these bags in their carry-on baggage. So, 3 (3.4-ounce containers) – 1 (one-liter bag) – 1 (one sachet per person). 3-1-1 for carry-on baggage = bottle of 3.4 ounces (100 ml) or less (by volume); 1 liter of transparent plastic zipped bag; 1 bag per passenger in the sieve container. One liter of bag per person limits the total volume of liquid each traveler can bring. The container size of 3.4 oz (100 ml) is a safety measure. You`ll be surprised to learn that you can actually carry travel-size bottles of alcohol in your carry-on baggage, or that you can`t wear creamy dips or spread them out as a snack in your carry-on bag if it`s over 3.4 ounces, but knowing these rules can help you avoid additional checks at the TSA checkpoint. The TSA exempts certain items from the 3-1-1 rule: medically necessary fluids, formula, and breast milk. You can bring more than 3.4 ounces of these liquids on board, but you may need to undergo an additional safety check.

Don`t forget your ID card! Worse than confiscating your liquids is realizing you`ve forgotten your driver`s license or passport if you`re already at the airport. All adult passengers 18 years of age and older must have valid identification to pass through the airport checkpoint. For most of us, that means driver`s licenses, photo IDs, or passports. Yes, toothpaste must comply with the 3-1-1 rule for liquids and gels. Toothpaste can be brought in your carry-on baggage by TSA security as long as it is 3.4 ounces (100 milliliters) or less and placed in a 1-quart bag. If your toothpaste is larger, pack it in your checked baggage or buy one when you arrive. You are allowed to bring a one-litre bag of liquids, aerosols, gels, creams and pastes in your hand luggage and at the checkpoint. These are limited to travel containers of 3.4 ounces (100 milliliters) or less per piece. Placing these items in the small bag and separating them from your hand luggage makes the screening process easier. Pack items in containers larger than 3.4 ounces or 100 millilitres in checked baggage.

Items in secure, tamper-evident bags must be inspected and released. Items that are alerted or cannot be checked in are not allowed in your carry-on baggage. We recommend that you pack all liquids, gels and aerosols larger than 3.4 oz or 100 ml in your checked baggage, even if they are in a secure, tamper-proof bag. Each passenger is permitted to carry liquids, gels and aerosols in 3.4-ounce or 100-millilitre travel containers.
