⚖️ 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.
