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.

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.

Plane was packed but flew on-time, and the comfort level was great! All planes are a bit cramped, but the in flight entertainment was superb, snacks were nice, and the crew was polite. Got into Calgary on schedule...all we could ask for

I am very tall. All airline seats are a bit uncomfortable.

Lots of announcements that no wheeled carry on bags were allowed on the flight, yet the overhead bins were totally full and made it uncomfortable trying to get through and significantly held up departure. Why were they allowed on when they said that they weren't? Trash only came by soon after service and I wasn't ready to dispose of it. I had to first hold on to it and after flagging and attendant was told to stuff it in the seat back! I have never run into the need to walk outside in northern winter weather at an international airport and wasn't dressed to do so in the cold pouring rain! I'm not thinking that I'll be back unless I hear things have changed.

No complaints l will always do Air Canada once they are flying where I want to go

Flight was delayed an ultimately cancelled. Took me close to 45 mins with an Air Canada staff to be put on another flight.

Boarding was particularly poorly done with disregard for courtesy, professionalism, and efficiency. Think mid 70’s bus station.

My trip was ruined by the restrictions hidden in their "basic economy" plan. I'd flown hundreds of times and never encountered a program that does not allow changes of any kind. I don't know whose interface hid this information more, but I'm unlikely to use Kayak or Air Canada again after that experience.

Air Canada staff needs to be trained in hospitality. Most flight attendants are with attitude. Air Canada needs to carry additional food on board especially vegetarian plates as this category of travellers are on the rise. This is necessary for long distance flights. Blankets are cheap. Seats are not designed well Lower back portion should be thicker. Everytime thr passenger at the back of me took stuff or put stuff in the pocket of the seat in front of them which is my seat, I could feel them pushing or hitting on my chair.
