Liquids. If you have liquid or gel personal beauty items or food products, pack them in your checked baggage. Space in your carry-on should only be reserved for 3-oz. bottles of liquids or gels. There is no size restriction on nonflammable liquids and gels that fit in your checked luggage.
Guidelines are in place for both carry-on baggage and checked luggage and bags are screened by the TSA to ensure compliance with its policies. The TSA 3-1-1 policy limits the amount of liquid permitted in carry-on luggage to a single, quart size bag filled with 3.4 oz. or smaller containers of liquid per passenger.
