Due to the strike by AC flight attendants, my flight was cancelled. Very disappointing! A refund is being processed. This was not a Kayak issue. I will be sure to come back to Kayak in the future.

Due to the strike by AC flight attendants, my flight was cancelled. Very disappointing! A refund is being processed. This was not a Kayak issue. I will be sure to come back to Kayak in the future.

It got cancelled and they haven't given me a flight back yet!!

Biggest problem for me is that I am Star Alliance Gold and they were not able to give me access to to Maple Lounge because of some computer glitch . It was management by information system. She could clearly see my status and still would not give me access because the computer woudl not let her. She should have override that be attentive to a customer and figure rhat out later

Great breakfast and coffee …..fastest bag service I have ever had in NOLA

Last minute cancellation, followed by last minute delay with the rescheduled flight. Both due to interval operation issues. Poor resolution.Very disappointing.

Late departing. Late arriving. More worried about limiting bags on board. Free beer and wine a nice surprise.

Flying in the Dreamliner is always comfortable. Though the food options for Air Canada aren't great.

Flight got delayed for no reason. And Air Canada was doing 3 boardings via the same gate. It was chaotic!

I n the Toronto airport I had trouble finding my zone. It was 47. I went from Zone 1 to the end of the line.didn't find it. Then saw my zone somewhat by accident over by where you first come in. Signs could be more helpful or more personnel directing people like me.

Wonderful airline. All staff were pleasant and helpful. What is sad is that it wasn’t grand gestures just everyday pleasantness and friendliness that are missing from the other airlines I have flown recently.
