Smoking is not allowed on airplanes as safety and environmental protection measures on board are to prevent fires and the release of harmful substances into the environment.
E-cigarettes are battery-powered devices that simulate the taste and feel of tobacco by heating a liquid to create vapor. Although e-cigarettes themselves do not produce smoke, they are still electronic products and need to comply with airline regulations.
Generally speaking, airlines require passengers to turn off the power when using e-cigarettes and ensure there are no flammable objects around them. In addition, some airlines prohibit passengers from using e-cigarettes in seats, aisles or restrooms. Therefore, it is recommended to read the relevant regulations carefully before using e-cigarettes and strictly abide by them.
