Check with your airline before bringing any alcohol beverages on board. FAA regulations prohibit travelers from consuming alcohol on board an aircraft unless served by a flight attendant. Additionally, Flight Attendants are not permitted to serve a passenger who is intoxicated.
Alcoholic beverages with more than 24% but not more than 70% alcohol are limited in checked bags to 5 liters (1.3 gallons) per passenger and must be in unopened retail packaging. Alcoholic beverages with 24% alcohol or less are not subject to limitations in checked bags.
Mini bottles of alcohol in carry-on must be able to comfortably fit into a single quart-sized bag.
