To add a different component into the mix. I was on a flight that went technical from CLE to ORD. The TA rebooked me 4 hours later on a United flight.
I was checking two bags, which as a PLT was no cost on AA. However on UA this cost me $50. I sent the receipt to AA Cust relations, asking for reimbursement.. and they refused... Twice.
I guess that AA just don't cAAre about having loyal pax these days
