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.

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.

Flight got canceled. Instead of the booking me for the next flight at night I was booked for the following day at a later time. I was able to fly out that night because I had to call and deal with a human!!!

My flight was delayed My connection was almost missed. My bag was lost My valuable items get damaged

Kept me waiting for hours with the excuse of aircraft needed to cool down and then cancelled.

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.
