Good boarding but extremely cold temperature in both flights (60 F!).

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

Delayed by 5+ hours and they give a voucher for only $20 CAD which isn’t even redeemable at any place with edible food. Then took almost an hour to clean craft after it landed. And nonsensical boarding delayed even further. We didn’t leave until 1:30am….

Crowded and tight fit on Rouge. Entertainment requires your own mobile device. Small bag of pretzels is only food for 3.5 hour flight.

Other than flights being cancelled and 3.5 hours late causing missed connections it was ok.

Was disappointed when landing in Canada was made to wait for over 1 hour with several other parents and babies for our strollers . The expectation was that the gate checked strollers would be there when exiting aircraft. This was not the case we were told to walk to a point and wait for them . After being left there and not being updated we were met with very hostile and rude air canada staff . There where no apologies or understanding even though all the children where very uncomfortable and the parents very frustrated as you can imagine . Instead the air canada staff at the airport where very rude and made an already frustrating situation much worse instead of trying to assure the parents that that were making effort to fix the situation. One gentleman in particular was very rude to some parents telling them to move when they were simply seeking information. He made the other parents including myself feel very uncomfortable. He also told a gentleman he was capturing images of everyones boarding pass when this was untrue as he was only taking a photo of the gentleman pass which was strange.

Boarding a bit chaotic, but that seems to be mostly about extra security in Lima, not AC. Left on-time, arrived slightly early. Good flight

The flight from Lisbon to Toronto was delayed and then our connecting flight in Vancouver was delayed due to “unscheduled maintenance “. We boarded and then had to get off the plane and wait. We were over three hours delayed in Vancouver and missed our final connection to Saskatoon. We were forced to overnight in Vancouver arriving in Saskatoon at noon the next day. That’s over a 12 hour delay getting home.

I want to thank Carlos at the Miami AC desk - he was amazing and went over and above to help us out. Thank you Carlos and all the best to you!!! You made our faith in AC feel great! Sincerely, David Cubitt

Flight was canceled due to mechanical issues. After a considerable wait in the queue, Air Canada customer service was very helpful to get us on another flight. I am disappointed to report our rescheduled flight is for three days from now. Three days of extra expenses and inconvenience is unacceptable.
