Damn - I was skeptical about this until today.
YYZ>YVR - #1 on the list after all the preceding upgrades processed - gave up and boarded since I had row 18 and didn’t really care that much about getting PY in a bid for J, and then saw that PY had 2 no shows - except I had wiped myself and boarded already…
Really thought a high traffic route like this wouldn’t have me get into PY or J but pleasantly surprised that I had a shot if I just waited.
