My upgrade cleared at the gate in YYZ, but all the good seats were occupied by YVR passengers.
That's very close to my understanding, but I thought that if there was upgrade space YYZ-YVR, but not YVR-SYD, that a YYZ passenger could upgrade YYZ-YVR, and be waitlisted for YVR-SYD? Is that done manually somehow, or am I mistaken?
