I have a flight scheduled for the end of May (TPA-PHL) for a wedding. As you might imagine they have now moved the wedding to the fall. I am not having a problem changing the ticket but I had previously purchased a F upgrade which isn't being carried over nor is the value being applied. I assume I have to change the flight and then request a refund for the upgrade, but I can do so before the scheduled flight takes place (I can request it now)?
