I have not checked every message so apologies if already covered.

Does this apply to trips purchased on other carriers with AA flight numbers? For example my recent trip purchased by AA has some record low nTPS...
EDI->HLR 12
HLR->CLT (AA) 256
CLT->STL (AA) 20
STL->ORD (AA) 31
ORD->LHR 586
LRH->EDI 39
(AA means AA operated)

How about purchased upgrades at the airport.

The terms in the email were not clear to me.
