Yes, vapes (e-cigarettes) have caught fire on airplanes numerous times, leading to strict FAA and EASA regulations in 2026. These incidents are caused by the lithium-ion batteries inside the devices entering a state called "thermal runaway," often due to a short circuit, physical damage, or overheating. According to FAA data, battery-related fires (including vapes, power banks, and laptops) occur on average twice a week across the U.S. aviation system. One notable incident in late 2024 involved a vape catching fire in an overhead bin, forcing an emergency evacuation on the tarmac. Because of this risk, it is strictly illegal to pack vapes or spare lithium batteries in checked luggage, where a fire could go undetected in the cargo hold. They must be carried in the cabin, where the flight crew is trained to use specialized "Fire Containment Bags" to extinguish them. In 2026, some airlines have even begun requiring that vapes be stored in individual protective cases while onboard. Using or charging a vape on a plane is also a federal offense, as the act of charging is a common trigger for battery failure and fire.
