Anecdotally, I have also experienced that same company refusing to provide the service I paid for. They effectively stole a couple thousand dollars from me, by canceling the flight I needed to get to a new job across the country. I had even paid to upgrade my ticket to business-class, for the first time in my life. There were a few days left until I had to be at the new job, but they didn't have another flight available that could make it in time. So, I booked a flight on a different airline and made it with plenty of time to spare. AA refused to refund the ticket, every time I contact them they've said "you canceled the ticket, so you are not entitled to a refund." What a bizarre company!
