My wife and I flew AA for the first time this past weekend BWI-DFW-DEN and it was definitely an eye-opening experience. Previously we've mostly flown Southwest or Airtrain for domestic flights, and after flying AA it's almost inconceivable why anyone would want to subject themselves to so much hassle: 1. Our flight out of BWI was delayed due to mechanical problems which would cause us to miss our connection in DFW so I called up the reservations line and an agent was able to put us on a Delta flight. 2. When we got to the airport, we had to go back in forth between AA and Delta check-in because Delta agent couldn't see our ticket in the computer system. Eventually, a supervisor had to come out to print out boarding passes. 3. On our flight back to BWI, connecting through DFW, we board and are about to take off until the captain informs us one of the planes turbines won't start up. So we head back to the terminal, and after a half-hour of sitting without AC, they tell us that we can try to get on the next flight which has about 60 empty seats. Now it is a mad rush of people trying to deplane to get on the next flight. We don't get on the next flight and we have to spend an extra night in Denver and have to miss the next day of work. AA is gracious enough to give us a meal and hotel voucher for our inconvenience. 4. So the next day our flight from DEN-DFW arrives late and we are rushing to make our connection, which of course is on the other side of the airport. However, we should have learned from our previous flights that we didn't have to worry because when we arrived they hadn't yet started boarding because the computer system was down! Is this a typical AA flight experience? Everyone is always raving about how the AAdvantage program is so great and the miles are so valuable. It seems to me that the only reason to fly AA is to be able to redeem the miles on other nicer OW carriers. However, missing a day of work effectively wipes out the value of the miles that I've accrued. Not too mention all of the stress and long hours on the phone. I am very hesitant to take another AA flight since they seem so unreliable. Unfortunately, I've already booked BWI-ORD-PVG (Crossing my fingers that we'll be able to make it there).
