an absolute disaster and nightmare on air condition. IT WAS FREEZING!! everyone around us had hats, hoodies, gloves outdoor jackets on. that segment of the aircraft had a fault I assume...no amount of suggestion to turn down the air con helped. otherwise all good.

Everything was very good, short delay Toronto to Regina on my return to Canada but not a big deal. Thanks Kayak, Dr. Ian Stewart

Boarded smoothly, took off on time. Entertainment screens were reliable and the movie library is abundant. Food better than wtst was served on the first leg of the journey by another airline.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

It was ok. Even after the airport bus took us to the terminal , we did not expect to walk 35 mins inside the airport to the gate . A 15 min walk is ok . Especially if there was any delay in TSA check which happens to is too then people can easily miss the flight.

Excellent bit seats are still a little too small and there's that $75 baggage charge.

Very disappointed with how we left Heathrow, and the service from Air Canada. When food was given, I was skipped by the attendant, and when I went to tell him, he just dropped the tray of food on my table. Leaving Heathrow and landing in Montreal were bad, which is not Air Canada’s fault, but the service itself was not good.

No entertainment. Luckily I was the only person in that row. Small seating

Speechless! How professionally running. I am so proud of Air Canada 🍁 👏 ..

I didn't use the entertainment feature. I can't fault that. That was my choice. I could have opted for a bigger seat. Again, my choice. The crew was excellent on all of my flights. I don't really fault the food choices. (I'm one that's grateful to eat). All of the flights left on time or arrived early or on time. Grateful for the assistance that I received when checking my bag at Heathrow. (It was early...hard to think)! I hadn't flown in 17 years. I would consider choosing Air Canada again in the future.
