Certain items, if brought onboard, must be transported in your carry-on luggage.

Federal law forbids the carriage of hazardous materials aboard aircraft in your luggage or on your person. A violation can result in five years' imprisonment and penalties of $250,000 or more (49 U.S.C. 5124). Hazardous materials include explosives, compressed gases, flammable liquids and solids, oxidizers, poisons, corrosives and radioactive materials. Other examples of items not permitted include paints, lighter fluid, fireworks, tear gases, oxygen bottles, and radio-pharmaceuticals. There are special exceptions for small quantities (up to 70 ounces total) of medicinal and toilet articles carried in your luggage and certain smoking materials carried on your person.

Spare lithium batteries for portable electronic devices and cigarette lighters must be removed from checked or gate-checked baggage and carried onboard the aircraft. Because e-cigarettes are designed to operate by creating heat, they are not permitted in checked baggage and must be transported in carryon baggage only. E-cigarette use is forbidden onboard aircraft.
