The agents at the Kelowna YLW airport were really grumpy. Same with oversized baggage person. Staff on the plane were great.

The agents at the Kelowna YLW airport were really grumpy. Same with oversized baggage person. Staff on the plane were great.

Flight was early. That’s the only positive I can share. I paid for wifi on the flight and it didn’t allow me to use any streaming services so it was a waste of $20. West Jet also lost my ski equipment on my way to a ski vacation. They told me it would be delivered to the hotel as soon as it arrived at the airport. It was never delivered. I had to pick it up at the airport on my way home. I am completely disgusted with my experience on west jet

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

Experience was good, the wifi hook up is somewhat tough

Great flight, great landing, nice staff. Our seats were a little cramped.

I will not be flying with westjet again. I was uncomfortable in my seat. The position made my back hurt so bad. My wife was able to fit the seatbelt around her with out an extension but was unable to put the tray table down or fit in the seat for that matter. Our bag was smashed and I spent two hours trying to fill out the application for a damaged bag before I gave up. The 80 photos I took would not work and nothing telling me the format to upload them as.. I made the mistake of unpacking the bag before taking photos so no claim for me. Next trip to Canada I will have to use air Canada.

Overall good experience. The wait for baggage at our destination was quite long, but other than that everything was good as expected

Airplane is too small. Crew, especially the flight attendant who looked after our area, was not at all friendly and a touch authoratative. She may have been the most gruff flight attendant i've come across in 40 years of business travel

I selected "carry-on" for a round trip on Kayak, but my return flight on WestJet did not include a carry-on and they would not allow me to add one. My only option was to add a "checked bag" which I had to wait for on the luggage carousel after landing. Not a good experience.

I was seated near a "stinky" person. That's not the fault of Westjet🙁😶‍🌫️
