Was told by MPC today that upgrade wait list can only be there till 5 days prior to departure, after that, wait list will be canceled and we will need to call in to see if seats are released or not, regardless of status.

Is this the usual practice? I am wait listed on HKG-SFO and YVR-HKG F upgrade from my J revenue ticket in early January. I am only allowed wait list till 12/30. And I can see that on my scheduled flights HKG-SFO still has 3F open, and YVR-HKG 2F open. But they still won't release just one seat to me.

So what is their usual practice of releasing upgrade F seat and wait list policy?

My trip last August to LAX was a lot easier with upgrade cleared 1.5 month before departure for both legs. So very confused now!
