Full Answer

The liquid restriction applies to any items in the form of gels, creams, aerosols, liquids and pastes, per the TSA website. Each traveler may only have one quart-sized bag, as of 2015. When a traveler reaches the security checkpoint, they must remove the plastic bag of liquids from their carry-on and place it in a bin. This allows the TSA agents to inspect the contents easily.

Passengers must declare the liquids allowed in larger quantities at the security checkpoint, which means letting the screen agent know about the liquids. The security agents may inspect those liquids individually, states the TSA. These items don't need to go in a plastic bag.

There are no restrictions with regard to the amount of allowable liquids in checked baggage, as of 2015. Passengers who want to bring full-sized toiletries should pack them in checked luggage to avoid problems at the security checkpoint, recommends TSA.
