In July of this year, our flight out of Detroit was slightly delayed due to a storm. We left a few minutes late, made some time up in air and landed nearly on time. However, there was no gate available in Dallas and we had to wait on the plane for about 30 minutes. We were told no worries, our flights were being held. When we arrived at the gate, there was a line of about 50 people and we were told by the attendant that our flight was told to leave early and there were no more flights out. Also that she was leaving soon for the day, and we had to go to another gate to get rebooked. We stood in line for over an hour. There was one attendant to take care of all these folks. We finally got rebooked to reach our destination, but were told there were no overnight accommodations and we would have to sleep on a cot. On cots - really? With a Senior and two small children? The next morning, they rebooked us twice because flights we were scheduled on weren't going to leave the ground due to mechanical issues. At this point we had been in Dallas airport for over 16 hours with only their airport junkfood to eat and no vouchers. I noticed a supervisor and was finally able to get my father to speak to her. Noticing the multiple attempts to get us to our destination were unsuccessful, she rebooked us on an oversold flight with priority booking. We ran to the next gate. Only to have them board the entire flight and not hear our names called. At this point I was scared and in tears. It was looking like a second night in Dallas airport due to an airline with poor planes and poor customer care. I later wrote AA about this experience and was told better luck next time. I wrote them again to express my feelings about their lack of customer care and was told, "We have received your most recent email and want to take this additional opportunity to apologize, once again, for your and your family's interrupted travel. I can understand your continued disappointment. After review and at the risk of disappointing you further, our position remains unchanged. I am sorry. Still, your comments enable us to understand things from our customers' perspective. It would be a privilege to welcome you aboard soon." Of course, I have no intention of ever flying American Airlines again; neither do my family members, nor do our businesses! It's not about the delay, it's about the complete lack of customer care - both during the experience and after! American Airlines simply does not care about their Advantage or frequent flier customers, or any other customer for that matter!
