Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

It was a smooth flight both in the sky and landing!

Fare was great, seat comfort the opposite as cushion was worn out. Ok for 2 hour flight, not for 4.5 hour flight..

For the price, it was a really good experience. There was no entertainment on board, so I couldn't really rate this, and I didn't order a meal. I appreciated that there was a free glass of wine.

Very bad, flight was cancelled due to strike and staff was unable to rebook us

Air Canada is my new fave airline..I plan to use when I can. No complaints at all just rave compliments for the staff and airline.

Strike pissed me n stranded in middle of no where

No paper towels in bathroom. Aisle seat difficult to get out of Other than those, excellent service

Plane was packed but flew on-time, and the comfort level was great! All planes are a bit cramped, but the in flight entertainment was superb, snacks were nice, and the crew was polite. Got into Calgary on schedule...all we could ask for

All good but I could barely get my arms and legs into the room in front of me. Have never been so cramped before. Plane left the gate on time, taxied very quickly and took off without waiting. Unique. Arrival on time. No problem
