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
