Is smoking allowed in airplane lavatories?

Smoking is strictly prohibited in airplane lavatories due to safety and health concerns. The ban is a crucial measure to prevent fire hazards in an enclosed space where flammable materials are present. Airplane lavatories are confined areas with limited ventilation, making smoking particularly dangerous, especially when considering the presence of oxygen systems and other highly flammable materials on board.

The overarching regulations, including those from the Federal Aviation Administration (FAA) and international aviation standards, explicitly prohibit any form of smoking on commercial airliners, including within the lavatories. This prohibition is not just a cabin crew guideline but a legally mandated requirement aimed at ensuring passenger safety during flights. By enforcing this rule, airlines can help maintain a safe environment for all passengers and crew members throughout the duration of the flight.
