Would like whole can of pop for 2. Treats were not great . The garlic pretzels were terrible for someone who can't eat garlic. Passenger was 84.

I was very excited when we were to arrive 19 mins early . However that did not last long since there was no available gate and sat there waiting almost a hour.

I found check in difficult because I could only pull up one passenger. I got help.

The flight was cancelled, which led me to cancel my entire trip

It would have been better if food is served on a 4 hours’ flight

Upgraded to sit at the exit door so good leg room.

Orderly boarding. The flight to Montreal was difficult to get to on time, but had help from staffer.

The food on this 5 hour flight was a cookie or pretzels.

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel

On the flight from Montreal to Calgary the flight attendant we had was excellent. Unfortunately I did not get her name but she made the flight very comfortable and enjoyable.
