I know most wide body missions within Canada are air craft placement for International flights or transfer for Maintenance;

Which got me thinking the Widebodies flying out of YYC; how are they transferred off to other routes or maintenance?

I don't see any YYZ-YYC flights and doubt they would fly it to YVR....

There used to be a daily YYC-YYZ flight on a 767, but I don't see it anymore? And, I'm not sure what you're asking but there are wide body flights from YYC to NRT and to LHR. I assume those played into the [former] YYC-YYZ route.

Widebody flights out of YYC happen to the following destinations: LHR, FRA, NRT, OGG.

The LHR aircraft does a number of LHR-YYC-LHR turns before returning to YYZ via LHR (meaning the aircraft is substituted in LHR.

The FRA aircraft is much the same as above mentioned LHR aircraft.

NRT flight is AC9/10. In prior years this flight originated in YYZ. Last summer the aircraft did a number of YYC-NRT-YYC flights before being swapped out on YYC-YYZ-YYC run, this happened on either Wed or Friday. Current YYC-NRT flight gets filled by a deadhead run on YVR-YYC.

The OGG airplane does YVR-OGG-YYC-OGG-YVR.

If one of the widebody flights goes mechanical, then a rescue deadhead flight originates from either YVR or YYZ while the original busted aircraft is fixed in YYC.

Yesterday, 164 was a 763.

As to the LHR and FRA routes, mostly they are 333. Sometimes in winter, 767. NRT 767.
