The last time I flew on AA was about 3-4 years ago. I was flying in first on Delta with award tickets and Delta had an equipment problem. They put me on AA first from ROC - ORD and then on AA first from ORD - SEA. I mention the first because of the service - NOT!
My wife and I requested champagne - I had being going throught some tough business problems and was really celebrating getting away. The FA gave the champagne to two teenagers seated across from us. Aftefinally flagging an FA down to explain the problem, she told us we already had our champagne - we had to let her serve food to the other passengers. when we told her she gave the champagne to the teenagers she argued with us and said no she didn't. she finally asked the two girls, they said yes, they were surprised but happy to get the champagne.
Never heard an "I'm sorry" or anything - got the glasses - then the FA's hid in the galley.
Really glad we were able to fly Delta back home.
