To whom may alcohol beverages NOT be served on a flight?

Alcohol beverages may not be served to any customer who appears to be intoxicated because serving alcohol to someone who is already intoxicated can lead to various safety and liability issues. Flight attendants are trained to recognize the signs of intoxication, and their responsibility is to ensure the safety and comfort of all passengers on board. If a passenger shows signs of excessive drinking or unsteady behavior, it is in the best interest of both the airline and the passenger to refrain from serving them additional alcohol. This policy not only complies with legal regulations regarding alcohol service on flights but also helps to maintain a safe and pleasant environment for all passengers.

Choosing not to serve alcohol to an intoxicated individual does not necessarily mean that they are barred from consuming alcohol entirely; rather, it is a precautionary measure to prevent any negative consequences that might arise from overconsumption of alcohol in a confined space such as an airplane. This is particularly important in a cabin environment where emergency situations may need to be managed by flight attendants.
