The trip was very smooth; the seat was quite comfortable, and the food was excellent and tasty.

Delayed for 15 min due to maintenance. We were asked to wait to board as a family, but took longer than if we were not asked anything.

It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

Flight was delayed 3 times. My luggage was sent to Saskatoon instead of Casablanca - airline got it sorted out in two days. Received $45 in meal vouchers to use in the airport.

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

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

Liked the lounge in Toronto. The filmed safety information featuring a tour of Canada was amusing, maybe confusing to those with out English or French, or flying for the first time. With a few exceptions, personnel were polite and helpful.

Horrible. Sat at the gate in the plane for 2.5hrs.

My screens didn't work on both my flights, while most of the cabin's did. Flights were OK, one took off over an hour late.

5-hour trip with just water and one cookie is not great: fruits and cheese,, salads, protein smoothie... It could be small but nourrishing No screen and no outlet to connect our electronic devices. If there were ,It would have been nice to be informed. Every instruction given in french by the agent on the plane was pronounced so quickly that despite french is my 1st language, I could not understand the instructions. Too fast, no intonation, no space between words. Most of the time, the english versions (my 2nd language) were fast but with breathing between words, good intonation and the information was much easier to understand.
