Tnx claim opened
Next is:
then AA.com/PPQ to file claim.
This doesn’t have the same time constraints as creating the claim.
Word of advice, submit the claim via email. You’ll get an auto response so you know they got everything. Takes 2-3 weeks for a response.
I’d also call Amex (maybe before you file the claim) and let them know what happened, and confirm if / that you should first deal with AA or go straight through them.
For my incident, I just dealt with AA and have so far been extremely happy with the outcome (just waiting for the check to arrive).
