Cons: "Seating was uncomfortable, cabin was cold and no blankets available, food was just ok, plane had lots of empty seats yet everyone was squeezed into 3 in a row making it uncomfortable, no updates from captain or crew as to where we were in the flight....."
Cons: "The baggage drop attendant was very unhelpful when I asked if she could help me sort out an issue (when I checked in online for the second leg of my trip, i paid for my bag then but they wanted me to pay again for my first flight) and just dismissed me and said she couldn't help, making me pay again for my bag. First time I've ever had an unpleasant experience with Delta."
Pros: "On time, great service, a lot of legroom."
Cons: "Nothing."
Pros: "Left on time all went well in Atlanta"
Cons: "Impossible to figure out what to do in Toronto at Canadian Customs. You move from secure to unsecure then back to secure. It’s a mess and nobody tells you what to do or where to go. Picture process took 4 times. Nobody tells you that you have to transfer your own bags from Delta to West Jet. I even asked in a Toronto and they said no and nobody in Atlanta told me to collect my bags. So bags never made it until the next AM. The West Jet rep was very good and located the bags and they were delivered as promised. You should provide 3 page detailed instructions on how to handle Toronto. I am a seasoned traveler by the way. I’ve never seen anything worse. I could go on and on."
Cons: "Z"
Cons: "was a difficult transition from delta to west jet in Toronto and we almost missed the flight"

Pros: "The staff is very friendly. Most pleasant airline I've flown with."
Pros: "On time as scheduled."
Cons: "N/A"
Pros: "Left early and arrived early."
Cons: "Smallest bathroom on a plane I've ever seen. Could barely sit down without my knees banging into door or wall."
Pros: "The flight attendant named Steven went so far beyond the call. He was attentive, he fixed our video system when no one else could and when he learned we were celebrating an anniversary he brought us a present. He was awesome!"
Pros: "same"
Pros: "Refurbished plane. Lighting was good"
Cons: "No TV screen"
Cons: "My suitcase was ruined."
Pros: "The flight was on time."
Cons: "This was an almost 6 hour long flight, LAX to OGG. The aircraft was older and for a 6 hour flight, they really should use a bigger and newer aircraft. The entertainment systems on the back of the seat worked sporadically and the PA system was too loud and every time the PA system was used while we had our headsets on, it was excruciating We had no warning in order to remove our headsets before it blasted into our ears. We were amazed that after paying a considerable sum for our tickets and being in the air for 6 hours, there was limited meal service and we were required to purchase a sandwich in order to eat. I fly Delta frequently and this was by far the worse flight I can remember."
Pros: "Overall the actual flight was good..landing was kind of hard but I'm alive so not stressing that"
Cons: "..but the multiple delays are ridiculous, I would not fly Delta if I had a feasible choice."
Cons: "No space in the seats"
Cons: "Very dated plane. First class seat was worn, crooked, and uncomfortable. No entertainment offered. Almonds or biscuit cookies were the only food options."
Pros: "The flight left on time and landed earlier than anticipated"
Cons: "The seats were narrow and very upright"
Pros: "Flight was very comfortable and had a lot of space to move around"
Cons: "The gentleman indicating on the loud speakers what zones will be loading first was very rude."
Pros: "Crew"
Cons: "3 hours there before the departure."
Cons: "Took 8 hours to get from Oakland to Los Angeles. Flight delayed then cancelled at Oakland. Driven from there to San Francisco. That flight delayed by 45 minutes. Got on board and then they neede 4 people to get off the plane since it was overweight. That took another hour. Bad day of travel."
Cons: "Not a fan of having "final boarding call" announced to run to the gate, only to sit on the plane at the gate for 30 min because of a scheduled delay at my destination. I know the flight wasn't very full, but that cost me an opportunity to eat dinner. I had to cancel a fast food order because I thought I'd miss my flight!"
Pros: "I liked that the security line experiences very mellow, the staff all around was very friendly and nice, the TV's were great and they had free blankets and headsets. It was a very relaxing experience."
Cons: "thought the cabin could have had more heat"
Pros: "Gate agent arranged flight via Salt Lake City and also gave me $15 lunch coupon for my troubles. She was awesome!"
Cons: "Dealing with West Jet to refund a mistake on the ticket purchase."
Pros: "That a delta plane actually had seat back video screens- First delta flight ever that I've been on that did. But every ones screen froze up just over an hour into the flight."
Cons: "Even though the Atlanta to Toronto arrived 'early' I had barely 20 minutes to get to the other plane- I would not have made it with out the amazing staff of weather and the Toronto airport. I use a wheelchair and even zipping through as fast as I could I was 15 minutes late arriving at the gate. I booked this flight thinking I had at least and hour and a bit between flights. Thankfully others on my flight were also late so the Ottawa bound plane did not leave on time"
Pros: "Ability to change planes with a 30 minute layover."
Pros: "the flight crew made our flight very comfortable and pleasant. One flight attendant ( didn't spot her name) had such a gentle sense of humour while serving us-it was nice. Flight attendants at times seem like strict teachers - so it was nice to smile and laugh - especially now with such fear of flying due to COVID-19"
Cons: "Boarding process could be a little smoother and less frantic"
Pros: "efficient crew"
Cons: "Wake people up when serving anything.. I have seen in some other airlines that one is provided with a sticker to place on your seat to show if you can or cannot be woken up"
Cons: "Updated screens for movies..."
Pros: "The crew members were extremely kind and caring"
Pros: "Yes, they are."
Cons: "If we have something to watch."
Cons: "Issue handling for delay"
Pros: "comfortable seats, wifi entertainment"
Cons: "Unable to upgrade delta flight because it was a westjet code share flight, westjet unable to upgrade delta flight because it was to be done on delta servers. I was finally able to upgrade at the delta check-in counter for a higher fee than usual (ontop of the perfered seat upgrade I already paid for). I waited 1.5hrs after takeoff before I called staff for a drink. Over 2hrs before they officially started serving main cabin drinks and snacks. There was some turbulence but they could have served people by hand without the cart. They had no problem serving first class before, during and after takeoff."
Pros: "I received great service and the flights were on time."
Pros: "Good"
Cons: "Seat space"
Pros: "Good legroom compared to other carriers"
Cons: "Almost 1 hour late leaving. No westjet connect, so no entertainment."
Pros: "I didn't!"
Cons: "Late, late, late! I was a prisoner in my seat."
Pros: "Most employees were courteous."
Cons: "Flights were delayed multiple times . boarding was slow, seemed un organized."
Pros: "The manager who finally helped me was friendly and listened the entire time even when I was angry. She was concerned and helped me the best she could. The stewards are always friendly"
Cons: "There was only one agent on to check tickets. I was in line for 45 minutes and when I got to her, she just said over and over, there is nothing I can do, your flight time was just cut off. I would have to wait until the flight the next day. Even though I had no bags and there was still 35 minutes before take off. I also told her I knew I would be late and so spoke to someone from Westjet he night before. She smiled like I was lying to her. Lines should not be so black and white. If she would have just processed my ticket I would have had 35 minutes to get to my gate instead of 10. When you are flying with half full planes there should really be better ways to manage customer service."
Pros: "Airport staff went above and beyond to get my mother through the airport. We had a tight transfer and they helped us make it to the gate on time."
Cons: "There was no time to eat. Nothing other than snacks. The time allotted was *barely* sufficient to get from gate to gate. We were starving when we got to our destination."
Pros: "Fairly standard flight. By checking in early was able to change seat closer to front."
Cons: "With baggage fees now in place, people are really over doing the carry-on & oversize bags aren't being caught by the airline."
Cons: "Plane seemed older and less leg room for a 6’4” guy. No TVs or monitors to track flight info."
Pros: "Boarded early and flight left ahead of schedule. Plane was clean and ample leg room in economy for a 6+ footer. Flight crew were amazing and friendly with a full flight. Will be watching for WestJet deals on all our vacations."
Pros: "Upgraded to Plus - it was great."
Cons: "Too bad we have to pay extra for Plus to get a reasonable amount of room."
Pros: "West Jet just runs a relaxed yet professional airline. They are just more laid back and accommodating. You can use any bathroom on the plane as well which is huge on those rare times you need to use it. They are funny and chatty and seem to enjoy working together which all translates to a less rushed and relaxed experience for us the passenger. I really can’t complain....I had an entire row to myself....the best you can hope for, when riding on a plain for hours that’s like winning the lottery!"
Cons: "No complaints for sure"
Pros: "Flight was good."
Cons: "Was boarding at C70 but only saw signs for 71 and C73. Asked Westjet staff where we were boarding and they told me (and others) that even though we were booked to take off from C70 we’d be departing from the gate labeled C73 and also labeled for a flight to Regina. Still got to Hamilton though."
Pros: "The crew was very friendly and funny"
Cons: "Everything was up to my standard"
Pros: "$200 WestJet dollar compensation"
Cons: "Waiting 5 hours to leave. Not checking for delays before boarding. 12 month expiry on WestJet dollars."
Cons: "It did not happen. Being transfered to air canada in Toronto was a night mare"
Pros: "The stewardess serving drinks was very pleasant. Thank You"
Pros: "Excellent from phone courtesy to every aspect of travelling with them."
Cons: "Well organized. Courteous at every step. Other airlines should emulate them in every way. Travelled all over the world and would rate them as best so far."
Cons: "airport did t have air conditioning and there is no room in the overhead compartments propeller planes are unreasonable loud"
Pros: "We survived"
Cons: "On an 8 hour flight there’s no complimentary meal. I paid for a meal and it was worse than free plane food and starved for the rest of the trip. The chairs were horribly uncomfortable with no lower back support and we were not even given pillows and blankets. There was also no free entertainment. I rented a tablet and had it taken away an hour before landing while I was in the middle of a movie. I might have been ok with that if the flight attendant had politely asked for it back rather than rudely waving and pointing while I stared at her blankly trying to figure out what she wanted. Next time I’ll pay a bit more for an airline that respects its passengers and our comfort."
Pros: "All staff I encountered were amazing."
Cons: "This was where the real fun in my trip happened. After my arriving flight got in 2 hours late and sat on the runway for 45 minutes because there was too many planes in the way for my plane to get to the gate I was not in the mood to run across the airport to go through customs and then through security (for the second time). However in order to make it onto this final flight that's exactly what I had to do. I also might add that it is incredibly stupid that connecting flights have to go through security again after deplaning, it's not like we're suddenly going to have weapons or anything so why waste that time? After I sprinted across the airport and got onto the plane the pilot announced that we were waiting to hear from the airport to take off. Long story short the poor pilot was trying to figure out what was going on but no one was even answering his calls. Eventually he realized that the plane hadn't been refueled and had to get a hole of them to refuel. At one point he must have gotten really frustrated because he left the plane in search of answers as the Toronto airport wasn't giving him any. Eventually after 2 hours of sitting on the plane we refueled and took off. On top of that my travel partner didn't get her luggage, we assumed that the Toronto airport lost it somewhere or something. Overall a complete nightmare."
Pros: "Speed of Service"
Cons: "Wish flight attendants were demonstrated more interpersonal skills."
Pros: "Friendliness of staff"
Cons: "Had an aisle seat but was disturbed 4 times throughout the flight. Not impressed"
Pros: "Non stop flight"
Cons: "Internet was faulty"
Pros: "Staff was kind and courteous. Entertainment system had lots of video options."
Cons: "Both flights were delayed. Needed to use own device to access in-flight entertainment. Charger was in packed bag and phone was low on juice so only got to watch for 15 minutes."
Pros: "Fantastic flight!"
Pros: "The plane was less busy so many people had an empty seat next to them. It was great for leg room and I slept the whole flight!"
Pros: "Nothing"
Cons: "The pilot on the Honolulu flight to Vancouver left some documents at the hotel and he had to go back to get them therefore delaying our flight to vancouver. This caused a lot of passengers connection flights delayed and rebooked to another flight later on that day. No apologies or compensation of time wasted was given. Food vouchers would have been nice. The new boarding passes provided also pushed most of us passengers back to the last seats at the back of the plane.. which was a very uncomfortable experience."
Pros: "Cabin Crew were nice"
Cons: "Very tight seating."
Pros: "The flight and crew were great, great flight. Arrived earlier then stated. I still enjoy flying in and out of Hamilton. Great airport. If I can book West jet again, I will, great airline. Took some great pictures from the aircraft. Thank you !!!!"
Cons: "Security, too much, even when we arrived, customs twice."
Pros: "Main stewardess was very pleasant. Not full flight so I moved back and had a seat to myself."
Pros: "I was 8 mins late to check in."
Pros: "Comfortable seat with lots of leg room"
Pros: "Nice crew"
Pros: "Crew was cheery, in-flight entertainment innovation evident, plenty of opportunity for water/snacks"
Cons: "We were heckled by gate crew about whether my dog’s carrier was too small for him. Many suggestions were made that we were subjecting him to animal cruelty, and that we were abusive to him. He’s 7lbs, so he can’t be much smaller a dog, and his carrier it turns out, doesn’t fit under WestJet seats, despite being within carry-on luggage dimension limits (their life jackets take up most of the legroom), and thus could not be any bigger. Did they want me to have a smaller dog, or a Euclidean space-defying carrier? I suppose they were suggesting that taking a dog aboard WestJet is abusive, because they certainly don’t provide adequate space for anything larger than a hamster, they hassle you about it, and they charge you $50 for the fun of it. One agent had the nerve to reach into his carrier without permission, unannounced, and invade his personal space, him being a rescue and very anxious."
Pros: "I flew through the air in a metal container across the country in the time it would have taken me to drive 400 km, so that's pretty neat."
Cons: "Provide complimentary movies West Jet. Parading around tablets to rent for $6 is a bad look."
Pros: "The crew and staff were great on the plane. Could use more staff at the checked bags area but overall good experience"
Cons: "More agents at the check in desk"
Cons: "I was able to download the WestJet Connect app on my phone which gives you access to tv shows and movies to watch on your own device during the flight. The app was free and easy to use and there was a decent selection. However, the wifi on board is not free so even though you could watch the tv show/movie - the sound did not work unless you paid for it. There are many other airlines that offers everything for free - it would have been a more pleasant if we were able to actually utilize the service."
Pros: "Nothing"
Cons: "They had a gate delay making 30+ people miss their connection. Refused accomodations. Now we are stuck at the airport with no nearby hotels available and no transport for our final destination."
Pros: "Great crew, West jet connect worked fabulously"
Cons: "Cramped space and airplane food"
Pros: "Seamless boarding"
Pros: "Crew was friendly and helpful. Inflight internet was a great plus."
Cons: "Nil"
