Pilot missed Fredericton airstrip on first go, so had to ascend again, turn around and try it again, successfully, albeit a little jittery...perhaps a new or inexperienced pilot. Not the greatest Air Canada experience. Delayed us even more.

Pilot missed Fredericton airstrip on first go, so had to ascend again, turn around and try it again, successfully, albeit a little jittery...perhaps a new or inexperienced pilot. Not the greatest Air Canada experience. Delayed us even more.

The floor plan on the website indicated I was selecting a seat at the front of the cabin with ample leg room. In fact, I was in the row behind it. I should have wondered when the seat was free to upgrade, but it meant I traded an aisle seat three rows back for a middle seat, which was quite cramped. The Internet didn't work and the live TV didn't work until the last half hour of the trip. On a night of World Cup soccer games, not good.

Canceled my flight in March and have been waiting for 3 months now without the refund after it was promised

Food abd wine was good and for the price this was a true bargain, relative to other transatlantic options. But it is still significantly behind my experiences with Air France long haul in both hard and soft product. But for the price air Canada to Europe from Vancouver is currently the best value of quality for the dollar cost.

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

Horrible, we were on a little DeHaviland 400 that was really small and shaky. I am 5' 4" and I had to duck my head to get in it felt like an old war plane.

Very good except paying twice for seat selection. Once when I booked and again when I checked in.

It might have been closer to being on time. Maybe next time I could fly from London to Toronto?

We did not have seat assigned until almost the very end of boarding and my husband and I did not sit together I don’t know why even though we bought tickets 3 months in advance and checked in very early. We were not standby and we were treated as we had stand by tickets. I will never fly Air Canada again.

Air Canada canceled my flight last minute and I gave me next’s day night time my flight. No accommodations at all. I have a function on Xmas eve. So I had to took rental car last minute.i never ever book a ticket with Canadian airlines at all.
