On board wifi or other entertainment. Landlines option was good but ran late to Pearson

It was crazy, boarded over a hour late from scheduled departure. Then when arrived in BNA issued with getting off the plane…over 1/2 hour. Not looking forward to flying Air Canada, ever again.

Extremely turbulent landing. Crew was friendly and plane comfortable. Airport and US pre clearance was understaffed

Flight was late leaving. Charge for luggage which still has not arrived and will be delivered in a week.

Lovely flight.....only cold drinks and no more complimentary cookies!

I hope they were able to assign my preferred seat on my connecting flight. Wasn’t sure if it was language issue or they just can’t.

It was good. Short flight and the crew were well organized. I find the seats a little close together. I am tall so more leg room would always be welcome.

Would like whole can of pop for 2. Treats were not great . The garlic pretzels were terrible for someone who can't eat garlic. Passenger was 84.

I found check in difficult because I could only pull up one passenger. I got help.

In flight entertainment system did not work across the whole plane for entire flight. Seats were very cramped. Cabin temperature was freezing cold. Crew was miserable and answered everyone in a short and barking manner. I’ve flown air Canada many many times and never had an issue. But this was unpleasant.
