Aircraft is designed with all 3 washrooms at the back of the plane, meaning that when there is service underway, there are no washrooms available and it gets very crowded at the back of the plane.

I was through check-in right away and on the plane before I knew it perfect in every way

Excellent flight crew. Very comfortable plane. Entertainment options on air Canada were great!

Flight was oversold. Seats assigned to multiple passengers. Delay 1 hour to sort out.

Good but I don’t received my bags yet is been 5days still no update

Boarding is always chaotic. Delay was over 2 hours while inside plane . Crew not very friendly

Congested seating area Toronto Poor announcements Terrible food in flight Limited entertainment options

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

Comfortable seats with good leg room. But not screens on seat backs.

I was rescheduled when I missed my flight due to border clearance issue

I never got to Lufthansa because of Air Canadas negligence.

The flight got delayed 3 hours from Montreal and we missed our connecting flight so it was a long journey

Flight was cancelled due to maintenance issues. It was a nightmare to get an alternate flight back home.

What could have been better was holding the flight when our ORD to FRA flight was a bit late. We sat at FRA for 7 hours. It takes time to go through passport control and to get to a gate at that very large airport. We went as fast possible to our gate but were too late. Cityline is a good provider other wise.

The crew and especially Patrick were amazing. Very helpful, kind and accommodating. I’d be happy to fly with this crew for all my Europe trips!

The service and food was excellent. The remote control for entertainment did not function properly.

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

Not bad. We had preboarding tickets but the preboarding was badly managed. We lined up behind all the parents with little kids etc and when we got to the front of the line the attendant deliberately turned away from us and ignored us until I asked to be allowed to go to the gate. She started telling us that we had to wait until I told her we had preboarding then she let us through.
