Flight was delayed but the real issue is how long we sat after boarding. Space very limited for an overnight flight and seatbacks didn’t recline so it was almost impossible to sleep.

Flight was delayed but the real issue is how long we sat after boarding. Space very limited for an overnight flight and seatbacks didn’t recline so it was almost impossible to sleep.

The staff made sure I was comfortable, moved me to a better seat with more leg room

Easy boarding and comfortable seating were plusses. Enjoyed the experience and good service from the captain and crew. Many thanks...!

Everything was fine, crew was great. Always appreciate an on-time flight.

Most courteous, helpful employees and all flights were on time.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

Lots of announcements that no wheeled carry on bags were allowed on the flight, yet the overhead bins were totally full and made it uncomfortable trying to get through and significantly held up departure. Why were they allowed on when they said that they weren't? Trash only came by soon after service and I wasn't ready to dispose of it. I had to first hold on to it and after flagging and attendant was told to stuff it in the seat back! I have never run into the need to walk outside in northern winter weather at an international airport and wasn't dressed to do so in the cold pouring rain! I'm not thinking that I'll be back unless I hear things have changed.

No entertainment. Luckily I was the only person in that row. Small seating

Speechless! How professionally running. I am so proud of Air Canada 🍁 👏 ..

No complaints l will always do Air Canada once they are flying where I want to go
