[Silent Bob]

Her trip wasn't ruined by the thievery of AA, it was ruined by a frequent flyer who forgot to call AA to say she wasn't going to use the outbound to miami, and to protect the return portion. It's a mistake many are prone to make, but usually frequent flyers are on the ball about that. Actually it would have been easier to just pay the change fee for an earlier flight to miami rather than go through all that, or have her try and possibly stand by for an earlier miami flight, with th eticket she had. So not only did you have to use miles, plus pay cash, but you went and bought a one way ticket, and on top of that your daughter had to pay MORE money to buy a new one way ticket.

Yea, next time just play it safe and simply pay the change fee to change the ticket.
