Airline reviews

WestJet continues to live up to budget airline status. The flight crew were not particularly friendly and just were not attentive. We were served cold meals, not initially given any cutlery, and served wrong beverage orders. Seats are not comfortable, especially for long haul flights, and there is basically no offered in/flight entertainment. Fortunately they did have a WiFi service which did seem to work for streaming and connecting kids tablets, but if you were not prepared you were left scrambling. Mix that in with the strike concerns leading up to flights, it made for a less than ideal flight (especially when comparing it to similar class in Air Canada for the outbound flight). Third flight with WestJet but not necessarily planning on booking again.

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

It was a poor experience.A decline in what I was use to when travelling internationally

Boarded on time and arrived early. Overall quick flight. Snack and beverage offered.

Delay caused us to miss connecting flight and 3 hour layover. All connecting flights my wife and I couldn’t sit together. Once arrived luggage arrived 4 days later

Terrible 12 hours delay Terrible We lost our suitcases No medication with us nothing

Enjoyed the A330 comfort, and the inseat entertainment. Horrible disembarking experience. No gate when we landed to sat on tarmac for 40 minutes, and missed my train.

Awful, I was bumped from my buisness class seat because the airline decided to forfeit my seat to a pilot and stick me in the very back of the plane. My flight was delayed by an hour, boarding took an extra 30 minutes longer then it should have, and the in flight entertainment system was broken for my entire flight. I have yet to hear from Air Canada with regards to a refund for my ticket so in total I'm down about $1400 dollars for my tickets. Moving forward if I can avoid using Air Canada in the future I will be doing so even if it costs me extra money.

Unfortunately, my experience with Air Canada was not as great as I had hoped. The flight attendants were not very friendly or welcoming, which made the overall experience less pleasant. I expected better customer service and a more positive attitude from the crew. I hope Air Canada takes this feedback into consideration and works to improve the passenger experience.

Flight was late missed our connection to Indianapolis no hotel rooms really difficult finding a room hope to be in Indianapolis one day late and multiple flights to even get there.

Fine and uneventful I got to my destination safely No inflight entertainment Seats are not very comfortable

No charger and no entertainment on the way back. The plane's super old-like 80s old-with zero TVs. At least the free Wi-Fi works, so definitely bring your iPad. Also, no meal on this 7-hour flight.
