My upgrade cleared at the gate in YYZ, but all the good seats were occupied by YVR passengers.
It remains my impression, however, that YYZ originating passengers will trump YVR originating passengers if they miss out on YYZ-YVR but space is available YVR-SYD.
They could not have cleared the YVR - SYD portion at the start of the YYZ-YVR window unless your request coincided with departure time for YVR-SYD. If the former happened, I will go back to AC and ask for further clarification because it violets their even playing field policy. However, if the window opened at YVR at Toronto departure time, then the playing field is evened assuming paxs from downstream...YWG, YYC, YEG.....have access to upgrade request at Toronto departure time for AC 33.
