However, do you really need to deal with the hassles of YVR connections?
If you use the direct YYC-NRT-YYC AC9/AC10 flights you free up two segments and make the TG BKK-BNE rt possible on a single ticket.
(Personally we love AC9/10 as an option to the YYZ-TYO flights when we need to stopover in AB)
