What are the guidelines for serving alcohol during flights?

Monitoring passengers for signs of intoxication is crucial for flight safety and maintaining a comfortable environment on board. Flight attendants are trained to observe passengers' behavior, as serving alcohol can lead to increased levels of intoxication, which may result in disruptive behavior or medical emergencies. By keeping an eye on passengers after serving alcohol, flight attendants can take proactive measures if someone appears overly intoxicated, including stopping further alcohol service, providing water, or alerting the flight crew to potential issues. This approach helps ensure the safety and well-being of all passengers during the flight.

The other options do not align with safety protocols and responsible service practices. Serving alcohol without checking IDs compromises age verification, while serving freely without monitoring can escalate disorderly conduct. Limiting service to the end of the flight could also prevent passengers from enjoying their drinks responsibly throughout the journey.
