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.

Ground personnel in better mood. Sounded agressive wrt carry on bagage sizing.

Just kinda of a bus ride … we could do better. Delay in the flight :(

It was just ok, after a weather delay and had to take 3 planes in one day I asked for another cookie and she said no only one per passenger, found that a bit pity after spending my whole day in airports and planes

It was great. Although when I got my luggage it was broken.

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.
