Crew was friendly and helpful; cabin seemed roomy even in economy class.

The flight attendants that assisted me were exceptionally nice, kind and helpful

Something wrong with the plane so had to deplane and waited over 2 hours to finally leave

AC needs to update their fleet. Too many mechanical issues, dated planes and too many delays

The flight was delayed for 4 hours and the airplane was really old cuz not one thing was working.

They charge 5 dollars for plastic headphones for a flight of 1 hour! Seats are awful. Service is terrible.

Nice crew - very small plane and uncomfortable, with no entertainment options…

was wondreful! just let me know what airline im flying in advance!

On this flight, we didn't even get water offered, nor any other beverage. Therefore we got a snack of pretzels. Flight was good and Air Canada a good airline

I would realllllly like to have been in a seat closer than row FORTY. Needing assistance - longgg way to walk down and back; then they put me in the middle seat-needing to get up for the window seat passenger to go to the washroom etc.
