I am taking HKG-YVR this Friday, 05 Feb. Booked in PEY and wanted to use a Bookable Upgrade, but was rejected. I also had an award booking in J, but has been on waitlist for the past several weeks. At check-in, I plan to use points to upgrade to J, and will see what happens. I doubt the flight can be full.
Returning on 26 Feb. Will report back on loads then.
