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?
