my carry-on bag was delayed and I did not receive it until the day of my return at the airport. This delay caused me significant inconvenience, as I did not have access to my personal belongings for the duration of my trip. I had expected to rely on my carry-on items, and being without them negatively impacted my travel experience.

I had expected to rely on my carry-on items, and being without them negatively impacted my travel experience.

everything was fine expect massive delays - not the airline’s fault

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

In spite of purchasing premium, I felt it was perhaps the most uncomfortable seat I have flown in. The base was either broken or poorly made and had no support. Even placing pillows and blankets on the seat (1D aisle) didn’t help. It made for a long and mostly sleepless six hour flight. Crew also were very loudly talking to each other through the night making it very hard to sleep. It was purchased for the price, so I get the risk, but was not impressed.

The checked luggage still hasn't arrived yet. 42 h later. We saw it being unloaded in the stopover location. It was. 5 hour layover so it wasn't a rushed transfer. One positive aspect, it was close to being on time and the crew that came on the clean the plane was very efficient.

Worst check in and bag drop off experience. Staff were incredibly rude given that it’s the WestJet system that is faulty.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

We were happy with our experience. The price for tickets was much less than Delta and we actually took off and landed a little ahead of scheduled times.

Seat back entertainment monitors would be nice. We did enjoy the In-Flight WiFi.

Friendly helpful crew but that did not make up for cramped, uncomfortable seating. Anyone over 5.5 feet and 150lbs is going to feel crammed into the tiny space they have allotted for seating unless you are a special rewards customer, then you get the properly human size seats. With the outrageous price of flying these days, even in economy, the very least they can do is provide you with a comfortable seating experience. Especially since if there is any kind of delay on the ground you're likely to be stuck there even longer than your scheduled flight time.

Could not understand what the attendant was saying during his announcements.

Due to the strike by AC flight attendants, my flight was cancelled. Very disappointing! A refund is being processed. This was not a Kayak issue. I will be sure to come back to Kayak in the future.

The WiFi was down the whole flight, a flight that had no on board of any kind

Terrible, it’s a mess with the strike. Couldn’t do the Smithers flight because my flight to Vanvouver was cancelled and there is no customer service help to get refund or help

They canceled my flight, I had to rent a car, drive 14 hours. They tell to go on line for a refund, but only offer $24 for a $210 flight and you can’t get hold of anybody by phone and no help from staff at the airport.

They went on strike before time and screwed us big time. Which is not fair. We respect their planned strike but why they went on strike ahead of time ??? Poor garbage management

It got cancelled and they haven't given me a flight back yet!!

It would have been better if it wasn’t cancelled

Premium Economy is best if you can't get upgraded to Business.. Not as good to sleep for red-eye flights, but does the job. More space for your legs and arms.. The food is also better and the service is almost like business.

Awful. As we were boarding we were told the flight was cancelled. Then had to stand in a queue for 3 hours to talk to someone at the kiosk of Air Canada. They were not helpful at all. No empathy. My issue is not with them striking but the total disregard for the chaos and distress late notice caused. No thought on the impact this has caused.
