Plane changed to one with no entertainment system or ability to serve hot meals

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

Terrible. First my return flight was rescheduled to a terrible itinerary. Paid for window seats where there was no window. All of my seats were mediocre or terrible despite paying in advance for them. Zero onboard entertainment- it didn’t work or wasn’t available. If it was available there were zero instructions provided. I also didn’t like being forced to check my carry-on luggage. Delta screwed me around on the way home with a 2 hour flight delay that caused me to miss my connecting flight so my luggage did not come home with me but had to be shipped on a later flight. Just grateful they found it. But Delta attendants lied about the delay - a supervisor at an info booth assured me they would compensate because it was the fault of the pilot arriving over an hour late but when I went to the boarding gate to get help with this they insisted it was a ground problem in Toronto and not Delta’s fault BUT another flight to Toronto was going around the same time with no delays and West Jet agents in Toronto said there was no notice of any ground delays at the airport (which I have on video). When I went back to the info desk to find the Delta supervisor she was gone. I had to run through Toronto airport asking any availabile West Jet staff I could find to book a new flight home as I didn’t have a connecting flight anymore. Baggage wouldn’t help OR give me my bag back. Because we were one of the last flights into the airport all staff had left. I finally decided to go through security to find an agent at a boarding desk and was lucky to catch one before she left to get booked onto the next flight home in the morning but I still had to spend the night in the airport. It was awful!!! I was scared, travelling alone and desperate to find help - which was a extreme challenge. Maybe 2 out of the dozen people I asked were pleasant. The rest difficult. I felt betrayed. Oh and I kept getting directed to the information desk in Toronto airport but no one was on staff and I used the phone to try calling someone but I kept getting useless recording. I will not be flying Delta or West Jet again. It will be a long time before I feel safe to travel again. Many tears. This was an awful and highly stressful experience.

No access to any entertainment No food other than a cookie or pretzels even tho flight was over the supper hour Seats very close together and very little leg room Staff was very good

Good. Would be better if the carry on baggage was free.

Horrible. I checked out myself that it seems that I can have a free carry-on. But they ask me to pay $75 when we are nearly boarding. It was tricky during check out that make you mistake that you can have a carry-on beside your personal item. Also they ask $75 in the airport instead of $35 during checkout. So the whole process is designed to make you this mistake

Westjet is one of the worst airlines in the world. 100% guaranteed to have flight delays and flight cancellations. Will never book again with Westjet.

Plane should have entertainment, instead of people paying to use wifi

Westjet has been absolutely terrible! Flights continually cancelled. Took 4 days to get home. Would have been 5, but we booked last flight with another airline after our Westjet flight was cancelled. Even pilot on original flight looked frustrated! Funny how they say cancelation is weather related, but they still have more than 1 other flight leaving to same destination on same day, but of course those are all full. This happened more than once on this trip. Two weather related cancelations and 1 mechanical. Not sure if the last flight even went ahead. Felt so sorry for families with kids and babies, and the older travellers. Felt like we lived out of suitcases and airports for days - SO RIDICULOUS! Next to no help from Westjet staff at airports, but it appears there is nothing they can help you with. Westjet has made it that they are unreachable when you need them! People were getting extremely frustrated, and rightfully so. Additional costs to us really added up, but Westjet literally DOESN'T CARE! Final straw was when we had to pay $1280 on a different airline (economy) trying to get home after another cancelled flight. Westjet will be refunding us a whole $140! Can't believe how this airline operates. We will never, ever use them again!

The only thing I didn’t like was how far away the gate was. I would have requested a wheelchair had I known.
