Exorbitantly overpriced ticket. Flight was delayed as per usual with air Canada and there was zero refund or compensation.

Because you didn't have the tarmac clear and then had to unboard a plane I missed my connecting flight to CLE. Cost me a day ... a 30 dollar hotel hamburger ... then the next day THAT flight was an hour late to arrive ...

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.

Delayed on the way in 2 hours!!! And now on the way home delayed then cancelled!!!!!

Delay in luggage again for the second time of the trip. I would not advise using air Canada or at least I will never check in a luggage. Luggage issue overshadows the nice crew members unfortunately.

The baggage drop-off for Air Canada in Toronto for passengers flying international was terrible. One of the worst experiences I have ever had. The line was ridiculous; there was no one to help facilitate people avoid confusion, and the baggage system for the line I finally ended up in had to be re-booted right as I got to it.

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.

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

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.
