If the refund is available under AA terms, you might need to call or tweet AA to confirm this is the case.
For the purpose of the broader audience as this situation is now resolved:
1. Prior to the day of travel, it is the ticketing carrier, e.g. BA which handles rebooking.
2. On the day of travel, it is the operating carrier, e.g. AA which handles rebooking.
