I had occasion to call AE yesterday chasing a missing credit for a JM flight KIN-YYZ on 30-June. I followed the rules (made sure I had an AC ticket, AC flight number, etc.). Because JM flights cannot be credited automatically, I mailed in my ticket & boarding pass on 12-July. My call to AE was approx 6 wks after my letter looking.

The helpful AE rep explained that the "new *A credit validation process" has the credit department a bit behind in their processing. She went on to say the are currently working on May flights! I was asked for a bit more patience.
