All aerosols, liquids and gels must be packed in clear plastic zip-style bags. The bag must be quart-size or smaller and the containers in the bag must be 100 ml or smaller.

With proper permission from a TSA authority figure, certain medications, baby formulas, baby foods and breast milk are allowed to be part of carry-on luggage exceeding 100 ml and are not required to be in the one allowed zip-style bag.
