Everything was on time, loading and unloading went smoothly, and the staff were positive. I wish the seats were more comfortable and had a little more space. I was in the middle seat and had to keep my elbows in so I didn’t bump my neighbour’s arms. Would not like a middle seat ever again. Would fly Air Canada Rouge again 👍

Easy check-in at yvr Pleasant flight crew More comfortable economy seating than usual

The flight attendants were lovely - very warm and kind. Really appreciated it.

I was happy with the screen in front of me, that for a long time it was just black and not visually distracting. Then I discovered that I could just turn it off if I wanted to. Then I found some simple games and was happy to play those. I was happy with the service too. I do wish I understood the zones though. I wish there was a way for us to board and disembark more efficiently, or at least to board more efficiently, like having all the window seats fill first from the back to the front of the plane and then the other seats? But I do realize that there are perhaps already hundreds of more industry specialized experts & analysts who have been looking at efficiency for decades! I just take the stop & start boarding process with humour and I happily sit to await a simple departure after all those around me have been standing or bending for far too long. You must be used to it, but it still mystifies me why people hurry up and then just stand there.

Not very comfortable when stuck in a middle with passengers that encroach on your personal space.

It was good. My original flight was delayed and they put me on and earlier flight to avoid missing my connection

Boarding, offer those who need assistance some time not to be rushed.

Excellent experience. Smooth boarding, flying and the staff was courteous.

Could have had available the ability to watch a movie , but there was neither any hardware or place to plug-in.

We didn't get any food, not even a snack. Besides of that the experience of flying with Air Canada was great
