dmfriedman, I missed this thread the first time around. IIRC, your interest in this was started because of errors on an AA code, HA metal flight. Did AA have an explanation for the discrepancy? Or did they correct the posting amount?

484 (base) + 121 (COS) + 500 (elite) = 1105.
Watch me come up 32 miles short for an award.
It appears what they did was give you 484 + 121 + 484. Could be a bug in their software...
