Airline reviews

Pros: "Pleasant staff"
Cons: "People get shocked from the rush of air soon after they board and close their air knobs overhead. The cabin was filled with lots of new bodies that had different ordour and perfume that it was good to have a strong ventilation but due to the strong air flow... Perhaps tell ppl to keep it open."

Cons: "Overall it was good"

Pros: "Crew was great"
Cons: "No entertainment at all, read the brochure a few times"

Cons: "My seats were preassigned and at 24 hour check In you have to pay to change from economy to economy into a available seat. Make no sense and is rude. Very disappointed in WestJet and I’m anElite member."

Pros: "Every thing"

Pros: "The food was good and the crew were friendly."
Cons: "We could have used more legroom between the seats."

Pros: "Crew was friendly"
Cons: "Tv"

Pros: "Landed early"

Pros: "Crew was great . Seats not so much,"
Cons: "Maybe a movie for everyone."

Pros: "Nothing"
Cons: "Always delays with this airline, hope their service improves now they have been bought out by Air Canada. Staff need training on how to deal with their delays, rather than the "I know as much as you" answer. Their staff have always pleaded blind ignorance when disruptions occur. AVOID."

Cons: "Food, food, food"

Pros: "Crew were very friendly and were having a good time during the flight, which was nice to see."
Cons: "No pillows or blankets supplied, luckily I had my own otherwise I would have been miserable. Worst surprise was that there was no food provided. On a long haul flight that was surprising, they should clearly say that on booking. There were snacks available for purchase, but not great."

Cons: "Total rip off. I won't be flying West Jet again if it can be avoided"

Pros: "Yes, the crew was very good."
Cons: "It would have been nice to have coffee on the flight. All they had to offer was a snack and a glass of water."

Pros: "Staff was lazy"
Cons: "Horrible check in Rude Not sure if I’ll fly WestJet Luggage was wet when it arrived Luggage took forever to come to terminal"

Cons: "More water and a tv like air Canada"

Pros: "Yes"

Pros: "Quick, easy, comfortable. No complaints"

Pros: "The crew was great overal. Great sport and attitude with humor."
Cons: "The flight in Ottawa was delayed twice which made me change my plans twice. The plane was also a little cold heading to Toronto. Otherwise the help from Paul getting checked in was fantastic. He made the bad situation of a delay worth it just talking with him and apologizing for the delay with true empathy . Thank you Paul"

Pros: "Friendly crew"
Cons: "That westjet q400 is an awful aircraft with terrible slimline seats"

Pros: "Crew and staff are pleasant."
Cons: "There was a typo in my reservation (either a WJ problem or a Kayak problem). As a result I couldn't do an online checkin and ended up getting a middle seat at the airport."

Pros: "counter staff were friendly, courteous. helpful. Flight staff were friendly."
Cons: "prop- jet was loud & bumpy while on the ground at takeoff"

Pros: "Flight crew remained jovial and pleasant despite the many issues."
Cons: "Mis messaging and changing/non factual information as the flight status changed. I had personal issues ongoing which resulted in a flight change, and having to go back to security multiple times, which would have all been easier if I had been told that I didn't have to run like a mad woman through the airport as the flight was already determined to be significantly delayed. West Jet tried......they just don't see to be able to know anything."

Pros: "I got to watch "The Post", which took the entire time of the flight. I've wanted to see that movie for months and didn't know how that would happen! Easy flight, good service, friendly crew."

Pros: "The friendliness, the options through the app with movies etc"

Cons: "Need more leg room on board"

Pros: "Super friendly staff, on-time flight, good entertainment options; very satisfied"

Pros: "Clean planes, positive and a bit funny attendants, easy in boarding. Service that is wonderful."

Cons: "first time taking a westjet flight and we sat on plane for 2 hours before takeoff. disappointing"

Pros: "The crew was amazing and the boarding process went smoothly and fast."
Cons: "There was no entertainment for those of us without a compatible mobile/tablet device (I have a Nokia, therefore can't access the app). As always no complimentary meal but that's becoming a norm in most companies - strange how the prices don't really go down though... Seats were hard and unconfortable"

Pros: "The stewards and stewardess were fantastic."
Cons: "Its a little cramped in the seats."

Pros: "Delayed 2hours 30 min"
Cons: "Never flying with wast jets any more"

Pros: "Entertainment was good"
Cons: "The flight was delayed over an hour and then after landing baggage took a long time to come in. There were a lot of people gathered by the time baggage arrived and caused chaos."

Cons: "Boarding outside with no notice or warning"

Cons: "Our hour-long flight home from Toronto to Ottawa was delayed by two days. WestJet provided a hotel voucher and food vouchers for one day but refused to refund us for a car rental that would get us home in time. While we made our own way home, we were emailed to say that our flight home was delayed twice more."

Pros: "I liked the friendliness of the crew and how accommodating they were of me and of their guests!"
Cons: "There was quite a delay on my flight and I didn’t get an email to let me know there was a delay. Because I happened to go to check in earlier, I happened to noticed the delay. I wasn’t happy about not getting an email. I called West Jet to find out about the delay and it took approximately an hour to speak to someone. When I did, the delay was explained as weather related and the reason for not getting an email was because they hadn’t gotten to it yet I believe. I wasn’t happy with that as a reply. The flight was then delayed again by several minutes. I would have appreciated some form of compensation as I was going to get a lift home from the airport and ended up having to pay for a taxi as I was coming in so late. In all other flights, I know west jet to be quite an accommodating airline. The crew was great, I simply didn’t appreciate how the delay was handled."

Pros: "Got a window seat Good deal on price from kayak"
Cons: "Delayed by 2 hrs Lost my luggage and no word on when it will be returned Never told us about why delayed"

Cons: "Didn't fly on the day I was supposed to fly due to delays. I had to figure out for myself that I wasn't going to make my connection and thus I went back home. We agreed to itinerary for the next day that had a 2+ hour wait at la Guardia and yet I still almost missed the N.Y. to Tampa flight due to delays out of toronto. Had to sprint from one terminal to the other. In Toronto we sat on the tarmac for 90 mins, and this was after dealing with security and other issues with checkin before i even got on the plane. For example, it was difficult to explain that i had already paid for my checked bag the day before. As a result I never got a chance to eat the entire day. And then my bag didn't get to Tampa until later that night anyways. Although the individual staff members were all very nice, there were institutional flaws that made two days very frustrating. I have some sort of debilitating delay on more than half my flights over the last few years, and rarely is there ever an explanation or compensation."

Cons: "It was delayed."

Pros: "It was on time. Quick to board."
Cons: "I’m used to entertainment."

Pros: "Friendly crew"
Cons: "Entertainment selection is lacking."

Cons: "Delays Boarding: boarding from both doors: back door and front door, but no direction from the crew to anyone. Ended up with passengers trying to get in the front from the back and passengers trying to get to the back from the front. This created another extra 15 minutes delay when everyone were stuck in the middle...The rest of the passengers waited outside in Canadian winter cold. On a flight already late."

Pros: "Short flight"
Cons: "Nothing"

Pros: "I like that I got the plus seat for no extra charge."

Pros: "film selections are up to date with previously released films"

The issue could not be solved and we had to change planes. On the second plane, the captain shared with travelers that "and two loose wires were found, so it's good we caught that and changed planes". What the heck?
