No that would be a way to get a free drink at the airport... You would need to go to the lavatory on an airplane to get a free drink there.
I guess there is no way other than flirting the F/A or having a reason for a compensation.
slightly off topic, but what's the drinking age on international flights from Europe to the states, while the drinking age here is 21 its 18 or even 16 in Germany for beer, how strict are the carriers when it comes to the drinking age? Especially American ones on international flights?
I flew Horizon Air last month from SFO to PDX. The flight on a CRJ-700 offered a free Oregon microbrew, regional glass of wine, as well as Starbuck's Coffee. Not bad for a regional airline. Flight time was just 1.25 hours or so. I was impressed.
At SWA we are allowed to use free drinks as a Customer Service tool. Say a family boards late on a full flight and I need to seat them together, I may ask passengers to volunteer to move to help me out. For those who do offer to move, as a "Thank You" I will offer them a free drink. Sometimes a passenger will have a bad Customer Service experience before they board....a free cocktail, when appropriate, is a quick and easy way for me to apologize on behalf of my airline and potentially save a lost customer. If I have passengers celebrating a special occasion(wedding, bachelor,/bachelorette party, anniversary). I will sometimes give a complimentary cocktail. As a matter of fact, if I know in advance I can order a complimentary bottle of champagne for newlywed or anniversary couples. Also, like most other carriers, we can give a free first round of drinks for a significant delay depending on the circumstances. The liquor minis are purchased for just cents...so it's a relatively inexpensive "frill" that I can provide a passenger despite that fact that we are a "no-frills" carrier.
Fly Midwest Express (3 yrs ago) with the crew scheduler and charter scheduler to Dallas for a bachelor party with 5 other of your closest friends, and have the cabin crew and flight crew buy a round (Only thing left onboard Special Ex)
