Who is responsible for ensuring alcohol is only served to compliant passengers aboard the aircraft?

The responsibility for ensuring that alcohol is only served to compliant passengers aboard the aircraft falls on the flight attendants. They are trained to monitor passenger behavior and serve alcohol responsibly during the flight. Flight attendants play a crucial role in maintaining safety and order in the cabin, which includes assessing whether a passenger is in a condition to consume alcohol without compromising their well-being or that of others.

While ground staff, pilots, and security personnel have important roles in ensuring overall safety and compliance, the direct serving and monitoring of alcohol consumption occurs in the cabin, where flight attendants are present. They are trained to recognize signs of intoxication and have procedures in place to refuse service to any passengers who appear to be overindulging, adhering to regulations and company policies on alcohol service.
