Everything was great until we had to get our bags. The bags came out in several different batches over 90 minutes after we landed maybe more we got our bags. So much for the old West Jet where they promised bags in 20 minutes. I Next time I will pack lighter and go with a carry-on.

Everything was great until we had to get our bags. The bags came out in several different batches over 90 minutes after we landed maybe more we got our bags. So much for the old West Jet where they promised bags in 20 minutes. I Next time I will pack lighter and go with a carry-on.

The flight was full and good as could be expected. We arrived early which is always a good thing.

They lost my bag. Hopefully it will be here tomorrow.

Not sure what happened, but for some reason we had to sit on the plane for an extra 10 minutes once we arrived in Abbotsford. Obviously, it was an engine issue.

It was disappointing to see the huge number of people who were allowed to board who were claiming to either be disabled or needed extra time to board who practically ran to the gate as soon as boarding opened. One of the female flight attendants in the premium economy section refused to let a lady with an infant use the toilet next to row 9 to change her baby even though the path back to the rear toilets was blocked by staff and trolleys and said she would have to carry the baby to the toilet during the descent phase when turbulence was present. The passenger refused and the baby had to wait until landing. It would have been no problem to allow this infringement of weathers petty rules. The flight was also very cold due to a cold draft throughout the flight from the bulkhead ceiling which was not controllable.

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
