First class upgades never work after a same-day confirmed change???
Almost every time, if I change flights at check in ("same day change") as a MVP gold, it will continue to state "first class waitlisted" on the phone app, but sure enough I can not find my name when I view the waitlist. Sure enough, I won't get the upgrade either.
I can call in every time and they will uncheck and re-check me in to fix the problem, but how come this is occurring, and how can I prevent it?
