I had and interesting conversation with AA today myself. My flights to SXM was supposed to leave this morning, and of course was cancelled. The card i booked my tickets on had been compromised sometime later after booking and had been replaced, so i thought i would call AA to see if they would process my refund and needed the replacement card number. The nice lady looked up my flight record and i could here her typing and typing, and kept saying sorry it will only take a few more minutes. She came back with sorry, your not eligible for a refund, because my flight schedule change was under an hour! I said mam, my schedule was cancelled. Reply, i can't help you, you could try AA refund on line, have a nice day!
