I love the 2 seats per row. More room. The crew were excellent.

It was amazing although they did bump us up to the front which gave us more leg room and a meal. The service was great! The staff were friendly. :)

Overall very good... staff were friendly and helpful. boarding was good for the most part, but a little hard to get our carry-on bags on there.... I think people should be directed to keep their coats and small bags with them until all the carry-ons are loaded, and then, if there is space, they can put their small bags and coats up top.. makes it much easier to put baggage up. i loved the internet feature, but the entertainment was not there unless you have your own Netflix or similar platform. My chair did not recline, which was very annoying, and the arms won't go up near the isle, which makes it tough to get in and out of the seat.

Staff were excellant. Only snacks served. Some turbulence so we were offered Free beer or wine.

The staff is always great. Just the fact that our flight was the only one delayed from Halifax when all other carries were still flying. It happen a year ago out of Toronto as well. All others were flying but our flight got cancelled 1 hr before the time of departure.

The only issue had when i mentioned about comfort was the man beside me was on the larger side and took about 1/3 of my seat where i was pressed against the wall/window of the plane for the trip.

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

Thanks for giving a beer to everyone in the seat infront of me and then telling me that I can’t have one because they are going to land. I guess I need to pay for a seat and then pick one in the very front of the plane

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

Awesome, the whole way through. Thank you, this is the new Canadian Airline benchmark.

We never had an experience they canceled the flight and they did not offer us an alternative flight. I had to book one on my own expense. They offered us food voucher and we could not use them at the airport it kept saying not attached to an existing flight. The people at the counter were rude and cold and they did not care about our situation

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.

Found the seats very crowded—too close together ! And waited a long time for our luggage All staff at both ends were excellent!!!

Flight cancelled and Kayak switched our return flight to a red eye. Ridiculous.

Will never book through you again. Very disappointed in the notices and action taken or provided when planes are rescheduled, enough to cause missed connections

Very good over all , would have been nice to have entertainment on the flight

Absolutely the worst airline I have ever taken. They lost my baggage and told me my bag tags had been cancelled. When my bags arrived days later I had to pick them up at 3:15 am. My return flight was delayed another 6 hours and they broke my bag. Westjet does nothing to try and make it a better customer experience and all the customers services representatives I spoke with were useless and incompetent. Never flying westjet again.

Easy self checkin and baggage drop. No in seat entertainment, but wifi and app worked well

Single flights to Cancun purchased through third-party, initially had issues printing luggage labels with the lady at the airport Pearson… Was super friendly and assisted quickly despite being very busy

Very old planes. Seats were not comfortable. Air was not on during the flight leading to incredibly stuffy conditions.

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.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

Terrible all around. Flight was late and airplane was very uncomfortable. The crew were unhelpful and hid in the back. Did zero work. No entertainment.

I booked and paid extra for exit door seats also pre paid for my luggage air Canada changed plains and I never got what I paid for and they made me pay for luggage again they also did this to my wife. They are the most unorganized company I have ever dealt with. I am sure I will never see the extra money I paid for the seats or the recharge for the luggage. They are subsidized by the taxpayers and don’t give a dam just a horrible way to do business

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
