I've read in another forum, that the HKG-YYZ non stop is not a polar route. It follows a similar path as HKG-YVR but continuing to YYZ. Even though the polar route is shorter in distance, the winds allow the route via YVR to be flown in a faster time.
That is interesting, but still doesn't answer my question, which is about YYZ
. Surely the winds can't be more favorable via YVR
in both directions, or can they? If they still need to refuel doing a polar route westbound, then Churchill, MB
would be a good choice. It is only 20 nm longer than the YYZ
Great Circle distance. YYQ has a 9,200' runway and has jet fuel.
