Airline reviews

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.

I wish Air Canada would provide a meal on the 5 hrs or more time flight to the passengers.

Terrible… Luggage’s missing for 5-days. Not expedited despite notifying them that insulin and ozempic were in bags and required refrigeration. I’m extremely disappointed. Meds were useless upon delivery as ice pack had dissolved and meds were warm and not useable because their efficacy and potency are now questionable . I’m so disappointed and expecting a full refund for the checked in bags.

Was delayed at every point/ connection. Luggages missing for 5days. Had no medications for diabetes and high B/p. when bags where finally delivered on the 30th, the insulin and ozempic were no longer patent, as the ice pack had since dissolved and the authenticity of the med is now questionable, since they must be refrigerated. Please have them refund my bag fees. I should sue them for all the inconveniences caused to me.

The plane was delayed substantially due to a mechanical problem, that being said, the airline was very fair with providing a meal coupon for us. I would rather arrive late on a mechanically sound plane than the alternative. The food served in the plane was just awful, however and I recommend a new catering company.

Very bed experience never want to travel air canada anymore

I liked all of it, and excited to do it again~* Thank you, and Much LoVe and Respect, CHRiS aka KRYSTOE 👣🎵 http://www.chrisrousemusic.bandcamp.com Google = chrisrousemusic and/or KRYSTOE
