What is the airline policy on smoking aboard flights?

• A. Smoking is allowed in designated areas only.
• B. Smoking and vaping are prohibited on all flights and aircraft, including cabin and lavatories.
• C. Smoking is prohibited only on international routes.
• D. Vaping is allowed in the cabin but not in lavatories.

Answer: (B)

Smoking and vaping are banned on every commercial flight. Airlines adopt a universal smoke-free policy to prevent fire hazards, protect passenger and crew health, and maintain a safe, comfortable environment from boarding to deplaning. Because there are no permitted on-board smoking areas, the entire aircraft, including the cabin and lavatories, must be smoke-free. That’s why the statement that smoking and vaping are prohibited on all flights and aircraft, including cabin and lavatories, is the correct one. The other options suggest allowances or exceptions—designated areas, only international routes, or vaping allowed in the cabin—which do not align with standard airline practice.
