The keg from Edmonton to Toronto My wife found it very cold. Other than that great flight.

No dogs! Can we have no dogs in the cabin? Why was there a yappy little dog behind me? Lucky I had ear plugs. Sorry for others without

Smooth flight Staff were courteous and welcoming upon entering and exiting the plane Pilot and crew provided frequent updates Leg space was not pleasant but manageable

Everything was good except I was a bit disappointed that I had to pay US $150 for bags.

Good value, minor delay due to waiting for inbound plane but they gave accurate information about wait time. Able to switch to a seat by my husband thanks to a kind flight attendant

Arrival at Comox from, London,ON 6 hours later... No bueano

Flight itself good .Landing at terminal3 and connections to terminal1,it is connections nightmare,specially for disable person

The seats very Uncomfortable, no meal and no entertainment for a 4Hours flight. Smooth Flight, Great Take off and landing. Superb crew!

Generally good. However. The flight left 30 mins behind schedule with no reason given.

Flight delayed, missed my pick-up had to Uber, plus missed dinner and medication, so sad!

What a silly survey to send - all AC flights were cancelled due to the strike so of course we did not fly yesterday

The WiFi was down the whole flight, a flight that had no on board of any kind

I wish to travel with Air Canada for my next trip

They were very attentive, polite, professional and great customer service skills.

Bad experience. My checked bag was lost during this direct flight….how does that even happen?

Business class was not worth the extra charge. Overpriced for slightly larger seat. Nothing special. Small older plane.

Bad experience flying with air Canada . Seats not comfortable . Checked bag was delayed and was bought home next day by airport employee. Had to buy toiletries since bag was delayed . No compensation was even suggested . Will not fly air canada again

When I came in the front door in Montreal airport I didn't know where to go, first time traveling. Signs were not directing me.

The AC could have been better . Other than that , all was good

Every person and every experience with Air Canada was excellent. All customer service was outstanding and done pleasantly. The notifications through their App were timely and informative. This airline shines. All other airlines should take training from them.
