Airline reviews

My original flight was cancelled -- but I have to mention the excellent service I was given by the agent working at check-in who found me an earlier flight -- and helped me navigate security, ensured my baggage kept up with the quick check-in and boarding process -- and just generally made the re-booking process a breeze. Thank you! On flight was fine, but we unfortunately meant no in-flight service -- no water, or coffee (it was an early morning flight...), but the crew was pleasant and accommodating throughout.

No in flight entertainment on a 750 mile flight. Made you join their "program" to get it. It was free on my first leg of the flight from Cincinnati to Toronto. In addition, there was brief period of turbulence that prohibited the crew from serving refreshments. They used that short interruption as an excuse to never serve drinks at all. They had ample time to do so and chose not to. They went around serving half cups of water instead rather than have their carts in the aisle with drinks.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.

Just a two hour flight... boarding was smooth and easy going... flight was smooth... crew very helpful... snack of pretzels was awful, that needs changed...

First message when all on board was that we didnt have a pilot, then they found one, then it was something about the bridge something not working, they will either fix or do manually. Flight of course was leaving late with all the cruise guests worrying about making it to their ship in time. Then only some luggage made it off the ship. Around 15 to 20 people waiting. 45 min later arrived except mine. I asked the rep at the luggage conveyor, he asked me my name. Then said it was not picked up with the first batch so they put it in a room. I was going to take public transport but now worried about time so took a taxi that cost me $65 USD

It was good. The tray on the seat was not cleaned from the previous flight. The seats are tight but I had no one beside me. The crew was great.

The flight was very smooth and good. Boarding was fast, but the staff was just decently friendly.

Air Canada flight staff are in contact negotiations and they are less than happy and it show. The process of self checking baggage is less than desirable with lack of support staff to help

My bag was sent to lost and found. It was taken out of the plane without asking passengers if the bag owner is in the plane. I had valuables in my bag. I am very disappointed at this behaviour

A sandwich and a drink would have been better thank a snack bar...
