The Priority check in in Toronto rivalled the poorest I've experienced. The young woman at the desk (7:30 AM, YYZ) was unfriendly and abrupt, behaving as though we were interrupting her day. Her inch long fingernails said it all....I really don't belong here. Other than that, WestJet personnel provided a good travel experience, especially in flight. I must say that the repeated announcements about the cabin being full and how folks should gate check their bags became tedious. WestJet should just offer free checked luggage and charge for carry on suitcases. It would save a lot of time and the voices of the gate agents.

The Priority check in in Toronto rivalled the poorest I've experienced. The young woman at the desk (7:30 AM, YYZ) was unfriendly and abrupt, behaving as though we were interrupting her day.

It was fine. I had a lot of trouble trying to buy a seat. The Westjet website charged me and then didn’t give me my seat. I ended up keeping the seat I was assigned and hope that the charges didn’t go through.. they didn’t. But this problem with the website (trying to purchase a seat at check in) has happened a few times before. But overall the flight was good.

My wife and I had an uncomfortable experience with your WestJet ticket counter rep at the WestJet Priority Member ticket counter at YYC (Calgary) on May 15, 2024. I not knowing this individual’s exact name, however, in order to easily identify her, she was one (of only two at the time) ticket counter reps at your Priority members ticket counter check-in, upon our arrival around 12:15 p.m. She was a Caucasian woman with blonde hair, and wore spectacles, approximate age being probably somewhere in her 30’s or 40’s. Background: After arriving in to the West Jet terminal in Calgary (YYC), I asked a terminal employee where the West Jet check-in ticket counter was. He told me, “Column 16”. My wife and I continuing to walk through the terminal, we finally arrived at the Column 16 area, i.e. this woman’s ticket counter area, which we discovered later was the Priority Member ticket counter. However, I was simply going by the directions given to me by the previous employee, i.e. “Walk to column 16.” Standing in her line (my wife and I being the only people in her line at the time), I tried to get her attention, and I then gestured to her, motioning to her as if to ask her if I should then possibly leave the waiting line in order to then proceed to walk up to her ticket counter. She never really motioned me to come forward. I sort of had to figure this out on my own, as my wife and I then finally decided to walk forward to her station. From this point on, after I arrived at her ticket counter, never once did she ever look me in the eye. She was always looking at her computer screen, or down at the ground, as she and I occasionally exchanged conversation with one another in order for me to be able to acquire my boarding passes from her. Shortly after she began servicing us, she commented that her work section is for Priority members only. Fair enough. I did not realize this at the time. Wishing to be polite, I then mentioned to her that, if I should, I could then walk over to the regular West Jet check-in ticket counter in order to complete the check-in process. She remained quiet, never responding to this goodwill gesture of mine. She continued to work in order to print out my boarding passes, and then finally handed them to me, never at all the entire time looking at me. I told her, “Thank you.” Never once did she respond. My wife and I then walked away. Even my wife commented to me afterward that this woman absolutely never looked at us. I cannot say that this attendant was outright rude. However, she certainly was not at all warm, congenial, nor friendly. Additionally, … After getting on the plane, we then discovered that she had needlessly assigned us seats in the very last row of the plane, these being the seats adjacent to the restroom back wall, thus, unfortunately not at all reclinable. I think that the row number of this last row of seats was 30. [However, I am not sure.] How strangely awkward that we were assigned these uncomfortable row of seats when in fact the row immediately ahead of us, i.e. I think that was row 29, had two vacancies, which could have otherwise easily seated my wife and me. That is, my wife and I could have easily been assigned these more comfortable seats, which would be reclinable, and then row 30 could have otherwise had instead our two vacancies. After our flight departed, and the fasten seatbelt sign was turned off, my wife and I had hoped to “jump seats”, that is, to leave row 30 and instead sit in row 29 to utilize the reclinable seats. However, another couple apparently had the same idea as us. That is, these other two people, for whatever reason, decided to leave their previously assigned seats, and instead, seat themselves in row 29. Thus, my wife and I were stuck with these miserably cramped row 30 seats for the entire 3.5 hour flight. To reiterate, the WestJet rep we originally encountered, knowledgeable of the plane lay-out as it appeared on her computer screen, could have easily assigned us the more comfortable row 29 seats, instead of the non-reclinable row 30 seats.

It was very, very cold extremely uncomfortable almost unbearable I was sitting at the front of the cabin

Too many oversized carryon baggage. If carrier reduced checked luggage fee this could be avoided. The staff were friendly and helpful, very professional.

Nice smooth flight with pleasant stewards. Slept most of the flight, they could have slowly turned on the lights to make it more pleasant. Otherwise a good trip.

Great! No food was available during the flight due to the catering service strike but snacks were given throughout the flight which was nice.

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Crew was rude.didn’t even say hi or welcome to board

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

Seating for almost 3 hours in the plan before aircraft takeoff. Very exhausted .

The bathroom did not have hand soap. That is unacceptable.

Moderate size plane, not completely full, easy boarding, some rows with just 2 seats so a couple can have a row to themselves

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

Once again my complaint is how close the seats are together. Also, the bathrooms were not very clean by the second half of the flight.

Excellent in flight service, perhaps the best we've ever had. Business class feels tired and needs improvement to compete with other airlines. The food looked good but tasted terrible. Check in was quick, the flight arrived early and our luggage was on our flight with us.

Terrible quality wifi and they charge a lot for it. They nickel and dime you for everything.

It took 5 hour to get a crew to D Ice the plan. We had to sit on the runway for 5 hrs. in Calgary. It snows most of the winter. No proactive plan. In addition, after 3 calls to customer service they couldn't figure out how to have my wife and myself sit together on her birthday weekend. Everybody kept passing the buck. No decision from customer service, luggage drop off or check in team. The experience was a complete mess! I don't think we'll ever fly on this airline again.

Of our SIX flights in my travel group, five were delayed, and all (except possibly one) were just company screwups. One traveler had her CARRY ON baggage put on another flight because Air Canada could not properly do "weight and Balance". Bags missing for a day. Another traveler never made it. Then, (humor here) the flagship airline of the socialist country has NOTHING FOR FREE on board. Expect to pay for pretzels, folks. How's that socialism working out for ya, aye? I might book air Canada in the future if I have a meeting that I REALLY want to MISS!
