Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Terrible experience. Flight was delayed then canceled. They had no clue how to rebook us. Had to wait in line to take to a gate agent for 2 hours. Absolutely terrible from start to finish.

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

Most expensive flight… and they are trying to pinch more and more money out of you. Baggage, snacks, pillows, headphones… — so many airlines do far better than this… surely a national airline can do better?

Overcharged by either United or Air Canada. Abuse of access to my credit/debit card.

We have already filed a formal complaint with Air Canada and are considering filing a complaint with the US Dept. of Transportation. Air Canada was impossible to reach in the two days leading up to our flight despite multiple calls and waits of more than one hour. Their website is designed to prevent reaching anyone and simply puts you into one doom loop after another. In the end, due to Air Canada's lack of communciation and unresponsiveness, we could not take this flight. Depending on how Air Canada responds to our complaint, we may never fly this airline again and advise the rest of the world to do the same.

I was in Business Class row 7 on a 787-9. Both times I didn't get my choice of food. Otherwise, excellent!

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

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