What is the minimum age to serve alcohol on an aircraft in the U.S.?

The minimum age to serve alcohol on an aircraft in the United States is 21 years old, which aligns with the legal drinking age established by federal law. This regulation applies to all individuals, including flight attendants, and ensures consistent enforcement of age restrictions related to the sale and service of alcoholic beverages.

The age limit is primarily established to promote responsible alcohol consumption and prevent underage drinking practices, both on the ground and in-flight. It is essential for flight attendants to be aware of and comply with this law to maintain safety and legal standards in aviation services.
