AA had a "soft" policy on my way JFK
Outbound, we were delayed 3½ hours so we got free drinks (and 8000 free miles. Thx AA
Inbound, I paid $4 for a bottle of red wine. Then, during meal service, I got a free bottle. Three hours out from JFK
, an F/A was bored and offered me a cocktail on the house.
I think that one free bottle of wine/drink/beer with dinner, and paying for the rest, is a good policy in monkey class. But if the airline has such a policy, they should announce it during climbout.
