I am glad to see someone else has noticed AC does not respect its operating hours when their own metal is delayed!
This has happened a lot at YUL TB and now its progressed to YYZ TB it seems.
But the last part is partically damning:
considering it was just as pricy as many other high quality airlines I have flown. Unless headed to a destination only they serve, it’s hard to think of reason to justify paying for its premium service
I do recall Ben Lipsey's assertion that they benchmark their quality with the finest European/Asian airlines...
