Under what conditions is alcohol consumption prohibited for flight attendants?

Alcohol consumption is prohibited for flight attendants while in uniform primarily to maintain professionalism and safety in the aviation environment. This rule is in place to ensure that flight attendants are always prepared to handle their responsibilities effectively, which includes responding to emergencies and providing assistance to passengers. Being in uniform signifies a readiness to serve and uphold the standards of the airline, and consuming alcohol could impair judgment and response times, compromising both personal safety and the safety of passengers.

The other conditions mentioned, such as during boarding procedures, while serving passengers, or during layovers, may have specific policies, but the overarching regulation emphasizes the need for alertness and professionalism at all times, particularly when crew members are visibly representing the airline in their uniforms.
