Under what condition may passengers consume alcoholic beverages on board?

Passengers may consume alcoholic beverages on board only if they are provided by the airline and served by flight attendants. This policy is in place primarily for safety reasons and to comply with regulations governing the consumption of alcohol on commercial flights. Allowing only airline-provided drinks ensures that the alcohol is served in a controlled manner, reducing the risk of overconsumption and ensuring that crew members can monitor passenger behavior effectively.

In contrast, allowing passengers to bring their own alcohol or consume homemade drinks without oversight could lead to inappropriate behavior or safety concerns during the flight. Airports may have different regulations concerning alcohol sales, and while passengers can purchase alcohol at the airport, it's the airline's policy that governs consumption on the aircraft itself. This structured approach helps maintain a safe and comfortable environment for all passengers and crew on board.
