What are the correct protocols for serving alcohol to passengers?

The correct protocols for serving alcohol to passengers emphasize the importance of age verification and monitoring passenger behavior. Checking identification is crucial to ensure that all passengers consuming alcohol are of legal drinking age. This protects both the airline and the passengers, as serving alcohol to minors is illegal and can result in serious consequences.

Additionally, monitoring passenger behavior is essential in maintaining a safe and comfortable environment on the flight. Flight attendants are trained to recognize signs of overconsumption or disruptive behavior, allowing them to intervene when necessary to ensure the safety of all passengers. This responsibility includes making the decision to cut off service to an individual if their behavior becomes problematic.

The other options do not align with established protocols and can compromise passenger safety and compliance with laws governing the service of alcohol.
