Airline reviews

Pros: "Crew were very friendly and efficient. The flight was uneventful"
Cons: "Free drinks. More options for free snacks"

Cons: "Seat didn’t recline all. I felt like a sardine. Seat cushion the most uncomfortable that I have ever experienced."

Pros: "The crew took care of my wife and I when our flights were accidently cancelled. Literally were the last people on the plane. It was unbelievable to see their efforts and patience. Completely grateful."

Cons: "flight was delayed 2 hours, could have been some better communication on the delay"

Cons: "Delays in boarding. Gate staff were on the PA for directions and were drowned out by the airport PA. No effort to clarify and re-announce so all passengers were confused when to board"

Pros: "Good crew and on time departure"
Cons: "Overnight flight. How nice it would have been to have blanket and pillows as provided by some airlines ."

Pros: "Good humoured , polite and attentive crew"

Pros: "Great crew"

Pros: "Comfort, timing. Customer Service!"

Pros: "I lost my phone and when I went to the airport information, they already knew it is for me."
Cons: "It's all right for a short flight"

Pros: "Comfortable seats. Nice staff."
Cons: "Poor entertainment. I usually watch movies on my iPad but there was no wifi and the available TV shows were not to my taste, the screens were small and not clear. The magazine was boring, no games to play. Flight delayed an hour for no apparent reason."

Pros: "The night skyline from above as you fly into LAX is simply awe inspiring with the miles and miles of lights everywhere you look. Quick flight and no hassles."
Cons: "The 3 rows of clubs seats ahead me were catered to quite well, but maybe a current dividing that and economy is necessary so you don’t feel so 2nd class."

Pros: "Decent flight."
Cons: "Entertainment system did not work. Also they said there is USB sockets at your seat but there were none."

Pros: "More leg room in seat than expected."

Pros: "Friendly staff"

Pros: "Great flight. It was like the plane wasnt even moving !!"

Pros: "The crew. Very friendly and helpful"
Cons: "The food. Pizza was bad."

Pros: "Airport counter staff v helpful. Crew were great. Helped lady with 2 kids. Looked after 1 while mom changing other."
Cons: "Need more seat room. No entertainment."

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

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: "The crew on the ground and in the air were great. So helpful and upbeat. Every attempt was made to ensure our comfort and safety."
Cons: "I was in a window seat next to a small child and her mother. They were both lovely, but I couldn't move for the bulk of the trip because they slept most of the way. Not the fault of the airline of course, but if there was a bit more leg room, it would have been a less claustrophobic trip. I used to fly a lot back in the 70s and early 80s and I don't remember ever being so uncomfortable. I have another trip flying back home at the end of the week, and, quite frankly I'm dreading it. Also, it was impossible to hear the captain's address, the on-board instructions, or various other announcements, in the airport and on the plane. Especially on the plane; the speakers were far too quiet to hear anything the captain said other than it was a nice day."

Pros: "The stewards were great however no TV anymore and meals because of cost cutting was where we thought it was lacking."
Cons: "Refer to above :"

Pros: "Wifi"
Cons: "Nothing"

Pros: "The crew was so friendly. They offered to check bags for free at the gate which is awesome because I didn’t have to worry about finding space in the overhead bins when boarding."
Cons: "Flight was delayed an hour, but it was due to weather, so it is really out of westjets hands."

Cons: "It didn't happen"

Pros: "When I stepped onto the plane, there was someone there to greet you. That was nice."

Pros: "The cabin crew especially the gentleman was great and friendly and accomodative"
Cons: "Babies crying lol"

Pros: "Fast friendly service. Aircraft was clean and in great condition."
Cons: "No entertainment, not even power for your own electronics."

Pros: "The attendants are nice."
Cons: "The flight was delayed for abiut 2 hrs and when we boarded the plabe the auxillary power supply tyat provides the plane with power when it's parked in the terminal was broken which meant the plane was freezing cold, where we were basically forced to sit for another 45 minutes due to some baggafe issue, before the plane finally turned on its engines and warmed up the cabin. This happened in Toronto during winter (-15 degrees Celsius).... Westjet service has been terrible."

Pros: "Nothing"
Cons: "Everything"

Pros: "very amusing male steward! (welcome to westjet flight xxx to cancun!")"
Cons: "well, someday i hope to be able to experience "first class!" travel, but all in all, quite adequate! i always try to fly westjet in canada."

Pros: "Was very windy when leaving Hamilton but the captain handled the flight so smoothly that I was able to sleep through most of it!"

Pros: "Flight was great! Just a bit slow on boarding, that ok , I understand. Out of Hamilton but better than Toronto."

Cons: "crying babies"

Pros: "Very cheerful and friendly crew. Made the journey very enjoyable."
Cons: "Nothing"

Pros: "Pleasant staff and adequate leg room."

Pros: "It was an hour and 10 minute flight, so there wasn't really much space for error. They still gave me snacks and drinks which I didn't expect considering how short of a trip it was."

Pros: "the connection time in Calgary was short, so overall the trip was verily quick. Generally, the flight was good, clean plane, good services."
Cons: "There was no food for sale on a 4 hour flight from Hamilton to Calgary the flight left at 6:30 a.m., meaning that one had to be at the airport by 5:30 a.m., and for me leave where I was staying an hour before that. It was a connecting flight in Calgary with almost no time in the airport so I didn't get to eat until I arrived in Nanaimo at 1:15 p.m., Ontario time. for health reasons - I'm diabetic, I wish I had known that no "real" food was available. I got a snack which I read had 50 calories, and I got a juice which I normally won't drink to maintain blood sugar levels."

Pros: "Excellent Customer Service"
Cons: "No healthy snack options"

Pros: "Haven't flown Westjet in years. Don't know why but I don't have sore kneecaps, was served great coffee, the stewards always smiled and had funny things to say, and the gate keepers were happy and honest. I'm going to be a frequent flyer now for sure."
Cons: "I didn't like....um....nope. no complaints"

Cons: "To be honest, our stuartess was very abrasive. To everyone."

Pros: "Most things"

Cons: "Flight was delayed and took another 45 min to leave once boarding was complete"

Pros: "Staff"

Cons: "Poor management and customer service."
