Cons: "No entertainment at all, read the brochure a few times"

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."

Pros: "Crew were very friendly and were having a good time during the flight, which was nice to see."

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."

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."

Pros: "This leg of the travelling was fine. I know I got fleeced on the price of the round trip to go home for a funeral but didn't realize just how bad until my seatmate told me he paid a third of what I did. Note to self: Don't ask the traveller next to you how much they paid for their ticket..."

Pros: "I went through customs and then walked via escalators and moving walk ways to b4. It took me almost a hour. I was the last to board I am sure And had to collect my own luggage and take it from one point to another. I am 70. thank god, when I got on the plane I sat in 3a and was offered a free glass of wine. halleluya. I was exhausted Toronto airport is always a nightmare. I travel a lot and will avoid this airport if I can. I do like West jet but Delta /west jet connection means I have to take my bag from one place to another and I walked miles and could have missed my flight. I am tired. I am going to bed"

Pros: "Korean air is very efficient."
Cons: "We had to rent a car to get to Ottawa because West Jet had cancelled all their flights due to weather. All Air Canada flights were operating. We waited in line for 2 hours at the airport for West Jet to tell us that we needed to call them regarding a refund. We called them and were on hold for an hour and 45 minutes. Then we were told we had to call the travel agent...we on hold for 2 hours. We then called Korean air and they told us they couldn’t contact West Jet-no one knew what the value of the flight from Toronto to Ottawa was. We were only provided with a refund of $4 (for the taxes) when it cost us $280 to rent a car to get to Ottawa. I will never book a flight with West Jet again."

Cons: "Boarding outside with no notice or warning"

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."

Everyone was great except for security in Calgary!!! Don't know what the deal was but they set a record for the slowest I have EVER been in. It took so s almost an hour and there were not that many people in line...it was epic"

Cons: "It was horrible experience going through the Vancouver custom. Some one decided to random check a brown guy traveling alone. Okay, I get it. I give them credit for profiling me. But, I was very disappointed that they only know and follow the rules in their book. Dumping the luggage and wallet on the floor and then asked me to put everything back was not gonna help you find anything. They need to be bit smart and have some people skills. I mean a car salesman is smarter than this custom officer. I walked in for random screening with great respect for those officers but walked out with zero respect and maybe worse experience of my life. If you mistreat a innocent person just have a courtesy to say sorry or give them a stuffed canadian bear. We can understand!! One last thing for custom or border officers, treat the people the way you wanted to be treated."
