Staff was nice, helpful, and did all they could. I understand economy seats are bottom of the barrel, but we're crammed in there with others in our row.

Staff was nice, helpful, and did all they could. I understand economy seats are bottom of the barrel, but we're crammed in there with others in our row.

Business class lie down seats on WestJet aren't very comfortable. Crew were excellent and overall flight was ok.

The seats very Uncomfortable, no meal and no entertainment for a 4Hours flight. Smooth Flight, Great Take off and landing. Superb crew!

Lots of overhead storage, good crew, good service, smooth landing.

Crew was friendly. Lost our luggage and told us it’d be in later in the evening of the day we returned. It was not. Still after 5 days have not received it.

crew was great, wifi was very poor could not even load a youtube video

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

First flight out in the morning is often the best chance of running on time. Not in this case, which unfortunately is now what passengers can expect as what is common. - If you are late for a flight, too bad for you. - If West Jet is late, too bad for you. - Bags don't make it? Too bad for you. - Flight change by 1+ days, too bad for you Prices continue to increase, while customer service nosedives. This is backwards and in any other develop country would be considered unacceptable - except for Canada. Too bad for us.

Experience was good. Was surprised they didn’t offer a complimentary meal on a 5 hour flight.

Too squished in seats. I'm 110 lbs and 5'6....can't imagine being any bigger and flying

Pros: The airplane was new and had in-flight entertainment (tablet behind seats) with new movies instead of watching on personal devices. Cons: the flight time was changed without informing us. When I booked the flight, the time was 13:30pm (also in the email confirmation). However, when I reached the airport, the time was conveniently changed to 14:55pm. When I asked at the counter, they said the flight always took off at this time. The booking was made by Air Canada, but the flight was operated by United.

The app was great, service was wonderful, everything was quick and easy

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

Your crew was so so so wonderful Only thing sound be great if you kept some phone chargers and converters rest 👌👌👌👌

The speakers were way too loud. Music was played during boarding too. This noise could've been avoided.

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.

Multiple change of the gates at Pearson, delayed flight was extremely uncomfortable.

Easy boarding, punctuality, decent service. I can only complain about the measly snack.

Never made this leg of the flight since we rebooked through United instead. Did not make it to immigration/US custom due to the delay. Had to spend the night on our own dime in Toronto

Booked flight was cancelled. Was rebooked but sat in airport for several hours for new departure.
