We were happy with the service and cost of checking a bag

Flight was delayed 3 times. My luggage was sent to Saskatoon instead of Casablanca - airline got it sorted out in two days. Received $45 in meal vouchers to use in the airport.

On board WiFi is a bit flaky. Good for streaming music but getting Air Canada’s entertainment to play was hit and miss.

I like the free air Canada wifi and being able to watch things on there. The basic snacks are good, just wish I could have both. If I’m being really picky, the flight attendant who filled my drink, filled it half with fizz and didn’t take the second to let it go down and add more, so I got maybe half a cup of pop.

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

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

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.

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...

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.
