Food good . No entertainment. Need to use wifi to access your own apps. Eg Amazon Prime, YouTube. They don't tell you unless you ask.

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

The ceiling leaked water on me. The toilets smelled very bad in the rear cabin

When I purchased the flights I included the luggage, the luggage was not added and got charged the full price anyway. Had to pay for the luggage at check in. Initial flight was delayed, we missed our 9am connection (flew with my wife), then the airline rebooks us to the next flights, putting my wife in at 1.40pm and me at 4pm, what a crazy wait time. We managed to fix it with customer service and they put me in the 1:40pm flight too, but they left my baggage behind in the 4pm flight. When arrived to my destination, of course no luggage. It was delivered to the address thankfully late at night. The experience sucked.

Very good experience. Great cabin crew. Much better than expected

Typical Canadian airline experience. Charger and tray were broken, food was poor quality, and yet you're still paying more than flights with equal to better service than elsewhere globally.

Not enough food option. And not enough advices or information about what we are gonna eat.

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.

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.

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