Ok, I thought I knew what I was doing but obviously am missing something. I bought a southwest airline ticket for $57.90 and it's still a valid ticket (never cancelled) and I look on my transaction and see two credits. One of $50 labeled as "AMEX Flight Credit" and another credit for $57.90 labeled as "AMEX Airline Fee Reimbursement". I expected the $50 but where on earth is this $57.90 from. I don't see anything in the benefits listing an airline fee reimbursement. Is the old "$250 annual airline incidentals end 12/31/2023" still getting credited or what am I missing?
