Currently, liquids are limited to 3.4 ounces per container with exceptions for essential items. Days after announcing that travelers would no longer need to take their shoes off for TSA screening before flights, Homeland Security Secretary Kristi Noem hinted at another possible change.

Right now, travelers can have liquids in travel-sized containers 3.4 ounces or less, placed in a one-quart resealable plastic bag. Anything else, except for medications and baby formula, must be placed in checked bags. The rules apply to liquids, aerosols, gels, creams and pastes.

Homeland Security Secretary Kristi Noem said Wednesday that the Transportation Security Administration is reviewing the long-standing rule on liquids in carry-on bags.
