Co will not do this. If you are not elite in the program you switch to you will even lose elite status.
I had people at NW say you are not supposed to be able to this-I always say based on what because the system clearly lets you. Anyway thats why I tend to it at the kiosk or online after the UG has come through.
CO could conceviabbly pull the UG.
