Original flight was canceled by Air Canada and next day they re scheduled and paid by hotel and taxi cost, but it just so tired for waiting and I have some school exam that I couldn't prepare it at all.

Original flight was canceled by Air Canada and next day they re scheduled and paid by hotel and taxi cost, but it just so tired for waiting and I have some school exam that I couldn't prepare it at all.

Delayed as usual with Air Canada. Checked the status of the fly online it said took off when the plain was still at the gate.

Not great. Missed my connection flight, due to AC issue. We were sitting on the tarmac for 90 mins before taking off.

Flight was delayed and rescheduled 3 times before being cancelled. Flight was also delayed on our flight in at Moncton airport on August 10th. Never flying with PAL again.

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.
