Just looked at the loads for the rest of May for both YVR and YYZ to/from HKG.
YVR - HKG appears relatively light compared to other times of the year, whilst the return HKG - YVR is full/oversold (overall Y and J) till the end of May. There was even a day where the airplane was oversold by 22 seats... it just amazes me they can do that, and yet still plan to oversell the following day's flight.
YYZ - HKG looks full for the next few days, then drops off a little. Ex HKG looks full till the end of the month.
