Thank you for that information MSPeconomist! I wasn't aware of it! I would hate to put someone out of their seat, but I will file it away for future reference
I have contacted AA so many times just to try and get an answer and a reimbursement for the one leg of the flight. I have basically given up. They do not respond to either FB, email, Twitter other than to tell me they will look into it and then nothing. Thank you all for helping me with this information.
