Taking liquids through airport security

Taking liquids through airport security

Everyone are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes in your carry-on bag and through the checkpoint. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item.

Do liquids need to be in a clear bag?

In short, the 3-1-1 rule is: 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”).

Why are liquids not allowed through security?

According to the TSA, limiting containers to what can fit inside a quart-size bag prevents what former TSA administrator Kip Hawley once called a “critical diameter” to blow anything up. The size of the container precludes enough of a potentially explosive liquid from being carried on board.

What is the 3-1-1 liquids rule?

Each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or100 milliliters. Each passenger is limited to one quart-size bag of liquids, gels and aerosols. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, mouthwash and lotion.

Why Do Liquids Have to Go in Clear Plastic Bags?

By putting all your liquids in a clear plastic bag and carrying it separately from your hand luggage, this enables security staff to easily see what liquids you have without having to root through your cabin bag.

Most airports will allow you bring your own bag ahead of time if you wish, and the only rules are it has to be made of clear plastic measuring no more than 20cm x 20cm. Liquids such as alcohol and perfume can be bought from Duty Free, even if they’re over 100ml.
