Crew were welcoming, accommodating and they worked hard to find places for all carry on.

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

l really enjoy very much the flight was very pleasant

Very thoughtful flight attendant offered me water immediately since I had run to make my connection.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

Brutal as can be … delayed by 24 hours then delayed and hour on the tarmac then delayed three hours in Chicago, screaming child behind me kicking the seat for the better part of 10 hours… couldn’t be worse

The entertainment wasn’t playing in the app or online.

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

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

So we didn't actually go. We were hoping to go for the Inauguration of the first female president. When That Guy got elected, we bailed. Unfortunately, we got basically none of our money back, despite having travel insurance. Would not fly with Air Canada again unless I had to.

This was my first time flying on Air Canada and the experience was good and pleasant enough, great crew members and the price I paid was amazing,

The Flight Attendant was particularly helpful to my wife, who was having a bad day.

It was fine. I wish their planes were newer to allow you to place your phone in seat in front of you to watch movies

It is air Canada so leaving 20 minutes late is very acceptable

The 1.5 hr flight was delayed for 2 hrs. And no coordinated

Other than the flight was a bit delayed, which I barely noticed, I had a very relaxing flight. I will definitely be using Kayak again

Everything was good but random change of gates and delays made me unhappy.
