Not sure what the agent meant by 'reticketing fee' being $75.. And no, she would not be able to process a points+copay upgrade at the gate anyway. After reading this thread multiple times, I'm not really sure what transpired. It seems evident that #1 and #2, through whatever upgrade means they used, were an all or none situation. #3 got the seat as a solo traveler. Then whomever requested the upgrade as a pair wants to change the request to send their companion back to coach while they still take the upgrade.
