Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

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

West Jet flight was cancelled and I was not notified. I found out when I tried to check in on-line. Spent 4 hours on the phone with West Jet and Just Fly trying to figure what happened.

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

Flight was on time. Online check in capabilities made things quick and easy. Zone boarding was enforced, which I appreciate. Everyone was not lining up ahead of their zone being called. Crew was professional and friendly.

The big lady was sitting right next to me and the button to recline my seat was blocked by her huge arm. No power outlet for chargers. No inflight Wi-Fi movies

Trip was uneventful which is good. Boarding took a long time due to many disabled/elderly requiring assistance which again is fine. Landing and take off were excellent. Food and entertainment were as expected, bring your own if you have preferences otherwise you get what you get.

Okay but not like typical first or business class. On domestic airlines

Our seats that I had paid extra for near the front of the aircraft were no longer available on this replacement aircraft. We were told we either had to accept the new replacement seats in row 27 near the back in seats E and B, no longer together, or sit in the very back in row 30 squeezed into E and F seats that do not recline or have trays that provide a flat platform for a refreshment. This is not what I had expected. However, again your flight crew did the best they could given the circumstances.

Overpriced. Exploitative price gouging. Appreciated getting bumped up to a seat with more leg room though.

Announcements were unintelligible. Entertainment system was non-existent. Ground crew kept changing story for flight delay.

After waiting for hours of delays, the flight was canceled. We missed our flight to Iceland from Toronto. We tried for hours to get a reasonable replacement flight, but it was the next day before we could even schedule another flight days later. We had to cancel our anniversary trip because we could not get to Iceland on time to keep our reservations. We won’t be flying Air Canada again as they just don’t have the infrastructure to deal with cancellations.

The only problem that I have is if you have questions about your flight ✈️ there's no one to communicate with when you call 📱.

As seems to happen every flight from Toronto to Ottawa we were delayed twice. We try to avoid Toronto when possible.. Denver to Toronto was fine.

Amazing and light experience, boarding on time, crew is super nice, clean salon and special thanks for movies availability. Provided by United Airlines

It would be nice to have access to the headphones since wifi wasn’t available. Passengers in front of me got them for free I was asked to pay for them. I heard stewardessa saying that headphones are complimentary since there is no wifi. When I requested headphones I had to pay. No room to sit. Bear given with the can but my drink was given in plastik cup. I will try not to fly with air Canada any more.

Had to cancel the flight because there was a 14 hour layover before the flight. Unacceptable.

The flight is very short, may be a little snack can be offered

They canceled my flight last minute, no hotel provided and they rescheduled Sunday night, hope they refunded some money
