Did a bit more checking this morning and it appears the planes both return to YYZ, the AC at 1:10p an d the ROUGE at 1:25p. Definitely booked the AC version and guess it will be a game of roulette to discover what I'll actually be flying that morning. Main issue is that I'd like to use 8 eUpgrade credits if it is a mainline 763 but certainly not if a ROUGE plane. (Booked myself in Comfort, only a few dollars more than Flex, and expecting the promo upgrade chart is extended beyond the end of this month for the reduced levels of credits required.) Both flights are lightly booked at the moment.
