Liquid or gel medications that exceed the 3-ounce limit may be brought on the plane, but must be declared to the transportation security administration worker when you go through security for extra screening of the product. Baby formula is also allowed to go past the 3-ounce limit. Clothing and other personal items such as blowdryers, curling irons and other styling tools are also allowed on the plane within your carry-on luggage.
