I will be travelling from Dublin to New York (JFK) using Delta Airlines.
I'm 20 and have been served alcohol on a summer flight without identification but that was Ethiopian Airlines and I have read that the original country of the carrier determines the minimum age policy. Since Delta is based in the U.S. is it 21?
Some say though that flight attendants are not fussy provided you don't look like an actual toddler/kid so age doesn't matter. What have you found through experience?
Officially, 21 is the minimum age for Delta flights:
For example, American Airlines confirms they adhere to U.S. law, telling Traveler: “Since we’re based in the US, we go by the 21-year-old drinking age.” Delta, United, Alaska Airlines, Virgin America, Southwest, JetBlue, Spirit, and Allegiant are the same, drawing a line at 21 and up for serving passengers alcohol onboard.
As a practical matter, they are unlikely to be too concerned about your age, and it's fairly uncommon to be asked for ID. If you're asked if you're over 21, I'd tell the truth.
