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.

The plane was almost an hour delayed and then once we were on board, they said that captain didn’t have enough hours left in his day to fly us so they had to find another captain. Surely that could’ve been figured out out in advance. Incredibly frustrating because I missed my connection in Toronto, and it has a result missed the first day of my conference in Charlotte, North Carolina.

Flight from saskatoon to toronto was by far the worst flight ive ever been on and roughest landing ever.

Mechanical issue caused me to be stuck in Vancouver for 2 days

The last 3 hours it was freezing cold in row 56. Multiple people had their winter coats on and were utilizing the blankets provided by the airline. I also did not have easy access to figure out how to book my food allergy and advance for my meals. Most of everything I received was something I couldn't eat. This needs to be made more accessible. Also, I'm 5'10 which is the average height of the American male. I flew from Philadelphia to Toronto and then to Tokyo and the seats were absolutely unbearable. For that long of a flight it is impossible to get comfortable when doing anything. Flights need to have more space and stop prioritizing costs over people.

The on-board entertainment system was horrible - we gave up watching because it just kept glitching.

Had to cancel the flight because there was a 14 hour layover before the flight. Unacceptable.

We had originally booked our flight from Punta Cana to London Ontario but our flight from Toronto to London was rescheduled and we would of had a 14 hour layover in Toronto before caughting our flight to London which is unacceptable. So we canceled our flight to London with no compensation and booked Robert Q Airbus from Toronto to London. We are not planning on using Air Canada for any more travel trips. In the last year and a half, Air Canada has rescheduled my flight from Toronto to London 3 times and forced me to cancel the flight and take Robert Q to London to avoid a long layover in Toronto. I received no compensation for the flight which is unacceptable. I'm very disappointed in the way Air Canada always rescheduled my flight from Toronto to London.
