⚖️ Why This Rule Exists: Inadvertent Activation & Lithium Heating Element Hazard Controls

Electronic cigarettes, vapes, and butane lighters contain heating coils and combustible fuels. Accidental activation in the cargo hold has caused in-flight fires. Therefore, DOT/FAA regulations strictly mandate that all vape devices and lighters remain in the aircraft cabin, with heating elements fully deactivated and spare batteries protected against short circuits.

Decision Threshold: Permitted in cabin baggage only. Maximum 1 lighter per passenger in the cabin. Checked baggage is strictly prohibited.

Bottles leak at altitude — put them in a sealed plastic bag even inside checked luggage, and leave some air space in partially used bottles. The device itself still goes in your carry-on, never checked.
