Changing after confirmed points plus upgrade?
I’m switching all of my UA flights to be credited elsewhere.
I’m currently UA platinum, and I have a confirmed upgrade using my points plus (economy to premium economy) on a HKG-SFO in the early fall.
If I switch to another program, will that jeopardize my confirmed upgrade? (Of course I know all “complimentary” potential upgrades won’t happen, just want to keep the premium economy.)
Thank you!
