Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Food choices were very limited. Taste of the dishes was average.

I liked all the informational texts. I always knew where to go and when .

Not as good as expected Air Can needs to improve totally rated on internet as worst

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

It was 4 hours late. Almost missed my connecting flight no food or drinks on connecting flight. Overall terrible experience

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

Paid $35 and not able to access the internet at all.

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Flight was delayed bc of mechanical issue. New plane had different configuration so some seats had to be switched. They called all passengers who needed new boarding cards. They did not call us so we thought our seats were the same and fine. When we boarded they informed us our receipts had changed and we are now all sitting separate and in the back row. Both my daughters had meltdowns and started to cry and once we got on the flight, we figured out how we could sit closer to each other, but this was very upsetting.

Took off on time and successfully avoided weather that looked to be a problem along the way

Internet on both flights was sketchy. Thus in flight entertainment was non- existent on MN - Balrimote leg.

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.

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

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

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.

it's all good nothing you can do make better 😌

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

It was so bad experience they wanted just charged passengers for any reason.

Delta was great. West Jet was not. I booked my flight in Sept (well over two months ago), but was told there were 2 reservations and NO tickets for me, my husband and 16mo daughter. We were unable to go ahold of West Jet over the phone and the kiosk was unhelpful so we had to buy completely new tickets in order to get home that day. I’ve called West Jet twice since and sat on the phone for over an hour without speaking to any representatives.

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.

Staff was friendly helpful also good timing I rate it a 10 out of 10

Flight was cancelled around 45 -1hr minutes before scheduled take off time due to mechanical issues we hadn’t even boarded yet. Had to reroute to Orlando so someone had to drive 2 1/2 to come and get me… the alternative was go through Toronto and get a later flight which didn’t work for my schedule. The flight attendants barely gave anyone a smile…not the same as flying when a client/passenger was important. Very disappointed. By the way I have never ever made a complaint online about any company with feedback…even when I probably should have. The only good experience was the boarding desk associates who were very professional and got me on another flight with my checked bags…very nice team.

Actually as my experience with air Canada from Canada to Newark it was crazy for me because it was a lot of delays which for me it shouldn’t be like that, but I was able to coup with it so that was my experience I hope next time they will do good on that thanks.

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.

Very smooth flight and the crew members were very welcoming.

The only issues I have are the seats are very small and so is the overhead storage. You should mention that while booking flights. I had plenty of knee room but I am wider than my seat, and I am not fat at all. The Mitsubishi 900 models need to be upgraded to western size people. I do not know how a 300 pound woman fit into those seats. I had to continuously lean away from the aisle to keep people and flight crew from bumping into my shoulder. 3 hour flight so no entertainment or food, just snacks and a drink, which was no big deal. The buttery/garlic pretzels were pretty tasty.

I was overcharged either by United or sister airline Air Canada. It's exhausting dealing with companies nowadays that irresponsibly abuse access to credit/debit cards.

Super. Planes were clean. Flights were on time. boarding was smooth. Flight attendants were professional.
