Westjet never disappoint always terrible small plane ,crowded cheap snack if you can call it snack

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!

I didn’t have any food but my Prosecco hit the spot. We left on time and the crew was friendly.

I thought the coffee was excellent! The wait for the luggage was acceptable.. It left and arrived on time. My son found that his device worked very well and he really enjoyed his flight! The stewardess moved him up to the emergency exit and he very much appreciated that!

I wasn’t able to book or pay for a seat and they forgot to check me in for my third flight so I spent 24 hours in Toronto waiting for another one.

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

The flight was cancelled less than 24 hours before departure. The alternate flight was a day later going from Grenada to Toronto to Vancouver to Calgary to Montreal. 2 days in the air. Not serious, Very bad service

I like the wider seats, Plus lots of legroom, Lacking entertainment, no tv or screen to play with

Liked in-flight wifi Did not like - nothing to complain, really. All good

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

Flight was first delayed for 1 hour, then was cancelled. Communication was poor. I ended up booking a new flight on a different carrier to return home. I heard people in my gate area on the phone with Air Canada customer service who had to inform them that the flight was cancelled and they weren't being helped because the system hadn't caught up with what was actually happening.

Other airlines offer free wifi to business class customers, Air Canada does not

Every flight was canceled and they didn’t care much about their passengers

Crew attitude and attentiveness. Comfort of the seats. Entertainment options.

this flight was exceptional due to the plane itself being updated with longer seat belts so no need for the extender and access to a tv.

Flight was delayed for over an hour making our connecting flight impossible to make. No notification that we had been bumped to another flight. Was told my bag would stay at the airport. Got to my hotel and got notified I needed to pick it up. Come all the way back to the airport to find I didn’t need to pick it up and the app glitched. They did at least put me on the next available flight. No offer for money back or compensation for time lost due to being home a day later. No compensation for food as it was only good for anything in the airport. Not outside it. They did at least book the hotel and the gate agent was very helpful. But I did not appreciate them giving my seats away to stand by people while I was sprinting through the airport to try and make it to a flight I was late for through no fault of my own. If they did not let stand by on I would have been on my flight as they did allow two people before me on

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

Good but I don’t received my bags yet is been 5days still no update

Comfortable seats with good leg room. But not screens on seat backs.

I was rescheduled when I missed my flight due to border clearance issue
