Airline reviews

For some reason pretty much all zones were called almost one after the other and we all ended up standing without moving for what seemed like a long time. Definitely not WestJet’s fault. Likely the guys in hiviz vests at boarding desk. The big problem was zero explanation. If there is a good reason for something people will understand. As a consequence of this delay flight was quite late leaving. Zero entertainment on board. I’m a Rewards member but was unable to connect to the Wifi. First world problems, I know. Flight was otherwise excellent.

It wasn’t bad but I swear their planes keep getting smaller and cramped so it was uncomfortable for such a long time. Also the food is just okay they need some different options

The gate personnel and flight attendants were all friendly and diligent. The poor attendants from London to Calgary were 2 colleagues short, as one of their team broke her leg on the way to work, and the other stayed with the invited colleague. I felt bad for the crew, but they did a great job regardless.

We purchased premium flex tickets for our overseas flight to London. I have food, allergies, so I knew I wouldn't be able to get a full meal. WestJet doesn't seem to provide any way for people like myself to register their allergies ahead of time. I was given one small package of crackers and cheese as my meal. I was told there were no more packages available and no other alternatives for food. The flight attendant seemed quite disinterested in providing service. That stands in stark contrast to other Westjet flights where the flight attendants have gone out of their way to provide service.

Delayed 2 days in London England - very poor communication from Westjet

Westjet food has really gone downhill- bring snacks and food of your own as the meals are very tiny and heavy on potatoes bread and rice. Pasta with a side salad of potato salad or rice/quinoa salad doesn’t make nutritional sense. Overcooked green beans. Both Protein and veg/fruit deficient.

The silly breakfast snack and SMALL lunch foodservice was pathetic.

Everything could have been better, crew didn’t smile once, seats were so hard, food was average

It was very pleasant to fly with WestJet! I would recommend to my friends. The crews were very nice too!

The plane was dirty and parts were broken. Really run down. My table kept falling down because the latch was broken. Flight attendants were just plain old mean. Don't waste your money going to Canada unless you absolutely have to. It's a hellhole.

great flights both ways on time both ways.staff(ladies) where great at check-in.

Flight was oversold. Seats assigned to multiple passengers. Delay 1 hour to sort out.

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

Very nice comfortable spacy Airbus 321. I liked the offer of food on the Bistro menu. The idea is very good to pay and cost was low.

I used to enjoy the travelling experience, but no more. We pay more and get much less. No air travel for me on the near future.

Easy airport. Luggage was late coming in but was handled quickly by excellent and helpful folks at Lost Luggage who got my luggage to me by 7 am the next morning! Bravo!

No place to chrge devices and no in flight entertainment

Delayed 1.5 hours. 1 hour due to plane late from Montreal and 30 min due to lightning storm. Seating OK. Entertainment modern.

We book an Air Canada flight but "got Rouged". Lengthy delays and 5 gate changes in a couple of hours. Cabin cramped, very little room in overheads. Food tasted stale. Generally awful except courteous and capable crew. Avoid Rouge like the plague.

Meal I purchased was disgusting. Fruit was spoiled and could not eat it.
