MiamiPrep

I flew these flights (MIA-DFW-ZRH) on 2/10. I am EXP, so received complimentary upgrade MIA-DFW, but when I arrived at gate in DFW, the flight was already boarding. Although my name was at the head of the list for ugrades on the TV screen behind the checkin counter, I asked the GA and she said that BC had already checked in full.
I had already had EXP pull the certificate for the flight so that part was already done. But sat in the exit row in coach for the long flight.
I also wondered if AA gives priority to people getting upgraded with miles plus the $250 co-pay fee, as this would generate more revenue than my eVIP.
