AirlineComplaints.org - Reservations Unauthorised cancellation of tickets by AA

Anyone ever heard of this happening before? Was on a family holiday in the florida keys last month. We had return tickets from LHR to JFK and took a connecting return flight from JFK to MIA with AA. Outward leg no problems. On 17th April, the penultimate day of our holiday, my wife tried to check in online with AA for our return flight from MIA to JFK only for the computer to show that our six tickets had been cancelled. Confused, we rang AA customer services where we were told that the tickets had been cancelled by phone two days earlier, and insisted that it must have been one of our party that had done so. This was complete nonsense of course. (Why would we want to cancel our tickets? We had our rental house and car booked until the 18th April and of course had a flight to connect with -JFK-LHR also on the 18th, and why would we attempt online check-in?) They refused to accept that it was nobody from our party that had cancelled and told us that the flight was now full and we couldn't be re-instated on it, and that there were no other available AA flights from MIA on the 18th. After a heated discussion and lots of prompting from us they told us that we could get a flight from Tampa to New Yorh via Dallas the next day which would get us there on time for our connecting flight home. We had no option but to take these. This meant leaving our holiday early and driving six hours to Tampa that evening in order to get the flight early the next morning, incurring additional fuel and hotel bills as well as other expenses and inconvenience. So beware if you have AA tickets, there is no guarantee that they may not have been cancelled and resold, leaving you stranded!!
