Staff was not frankly. I asked about what beverages you have and air hostess told me like before so very rude answer.

I liked that the plane landed safely. I didn't like that the food and leg room is horrible.

Business class was not worth the extra charge. Overpriced for slightly larger seat. Nothing special. Small older plane.

Bad experience flying with air Canada . Seats not comfortable . Checked bag was delayed and was bought home next day by airport employee. Had to buy toiletries since bag was delayed . No compensation was even suggested . Will not fly air canada again

When I came in the front door in Montreal airport I didn't know where to go, first time traveling. Signs were not directing me.

The AC could have been better . Other than that , all was good

I booked my flight months ago, and checked-in online about 12 hours before the flight. I received an email confirmation of check-in. I had no subsequent communication from Air Canada after my original booking. After arriving at the airport three hours before the flight, as instructed, I waited 90 minutes for an agent to appear to check my bag. I was informed that my flight had been canceled many weeks before, and that flight was no longer being run!! I showed a copy of my check-in confirmation, but no explanation could be found. I was placed on standby for the next flight and the connection. Luckily, those flights were not full and I arrived at my destination. I double checked my email, but I received no update about the flight from Air Canada until the day of the flight.

Every person and every experience with Air Canada was excellent. All customer service was outstanding and done pleasantly. The notifications through their App were timely and informative. This airline shines. All other airlines should take training from them.

The space for seats were uncomfortable and lack of leg room . I paid extra for more leg room. I’m not a big person.

Lack of WC assistance when returning to Toronto and my 92 year old aunt needed. To walk a fair distance with great difficulty to get to the exit and taxis. We were left without assistance after departing from the airport wagon.
