Is there a drink limit on Delta?

Alcohol or liquor is permitted if it's in your checked baggage or purchased after the security checkpoint for your carry-on, as long as it meets carry-on guidelines and the following: Alcohol content may not exceed 140 proof. Up to 5 liters of alcohol per person between 48 and 140 proof is permitted.



On Delta Air Lines in 2026, there is no fixed "number" for how many drinks a passenger can have; instead, the limit is based on the Flight Attendant's discretion regarding safety and sobriety. According to FAA regulations, it is illegal for an airline to serve alcohol to a passenger who appears visibly intoxicated. On long-haul international flights in premium cabins (Delta One), the supply is technically unlimited, but crew members are trained to monitor consumption to prevent air rage or medical issues. For those bringing their own alcohol, you can pack up to 5 liters of spirits (between 24% and 70% ABV) in your checked luggage, provided it is in original retail packaging. It is a federal offense to consume your own "personal" alcohol while on board; all drinks must be served by the cabin crew.
