Scores according to KAYAK customer reviews
Pros: "The entire flight and crew were very kind and friendly"
Cons: "Better snack/meal option"
Pros: "Very kind. Gave my daughter an extra snack because we had not had a solid meal in a while."
Cons: "Boarding process is never good. Obviously need to board the plane from the back to the front in reverse numerical order."
Cons: "Like all airlines it would be nice if there was an extra inch between the seats. Also, unfortunately the video wasn't working."
Pros: "Crew was excellent !! They ran a tight ship!"
Cons: "Seats need to be replaced ... no padding!"
Cons: "The quality of the video streaming was really low. It was disappointing."
Pros: "Very friendly crew"
Pros: "Wifi Decent snack More then 1 drink in plastic cup. How about full can TV working"
Cons: "No smile on your staff They look frumpy in their uniforms like nuns"
Pros: "Crew was efficient and friendly. Everything went well."
Cons: "Crying baby on board ..."
Pros: "Flight crew were all smiles."
Cons: "Delayed because something was frozen to the plane. Then delayed again getting de-iced."
Pros: "The crew remained quite calm and polite in a stressful situation, and they gave us free food and drinks for the inconvenience."
Cons: "There was an issue with plane's landing gear so we were delayed by over 2 hours (where we just sat in the plane on the tarmac) and we had to fly with the landing gear down the whole time. This meant we had to fly at 12,000 feet the whole time so it took longer, no luggage was brought on the plane, and passengers had to be moved around to redistribute weight, but we were never really told why or what was going on in terms of how it all worked which was quite scary. I'd say close to half the passengers actually got off the plane because they didn't feel safe flying. We got in over 4 hours later than anticipated with 0 luggage. Overall the flight was very scary and now we have no luggage. Had the option of having out luggage delivered the next day or a $100 travel credit. No credit or any compensation if the luggage was delivered."
Cons: "I’ve been at the airport since 9am, it’s almost 9pm now."
Pros: "I got the executive treatment"
Cons: "LATE TAKING OFF FROM WPG BY 90 MINUTES -- SEE ABOVE COMMENT -- YOUR SURVEY SHOULD NOT ASK ABOUT TWO FLIGHTS IN THE SAME EMAIL!"
Cons: "Missed my flight and i had to buy a new ticket to Saskatoon."
Pros: "I'm trying real hard not to give WestJet a hard time but my seatmate had genuine mobility issues and the walk to the gate AND out to the plane which was unusually far from the terminal...little help here folks!"
Cons: "Boarding attendant demanded to see my passport for a domestic flight even though I had produced the government-issued photo ID required."
Pros: "Crew was great."
Cons: "Plane was uncomfortable.trays were stained and dirty looking."

Pros: "Got me home!"
Cons: "Had to walk from the terminal to the plane in -18° !weather"
Pros: "This flight had individual screens!"
Pros: "Great service all around."
Pros: "My first trip started on a poor note; I got to airport about an hour before boarding, only to find out that my flight was rescheduled from 9:30am to about 6:15pm ( or so) on that same day without prior notice. I went up to the counter and asked for confirmation for the switch and inquire if there was an issue, which may have affected my original flight. Turned out that the change was due to weather conditions at Toronto (makes sense). I had suggested that it would have been nice to receive some sort of notification, before starting that day way too early and inconvenience of going to pickup my car from the airport parking, only to come back again. The attendant sympathized with my plight and compensated me with a lunch voucher (which was nice of him and WestJet). Matter was resolved; I came back to catch my flight and the trip was wonderful :)"
Cons: "I didn't like the fact that my flight was rescheduled without receiving any notification from Westjet."
Pros: "Re-booked on Westjet after my WOW airlines was cancelled. Didn't know what to expect - pleasantly surprised, Great service from top to bottom leaving Gatwick Airport. Will make them my top preference in searching future flights out that way."
Cons: "Nothing - the entire experience (check-in, flight, deplaning) exceeded my expectations."
Pros: "Everything went according to plan - left on time, arrived early, luggage arrived. What more can you ask? :)"
Pros: "Getting into Victoria befor evening"
Cons: "Delayed, no pilot, no communication."
Pros: "We took off, we flew, we landed and walked away."
Cons: "5hrs and 9min flight time. Add boarding and alighting at the other end - adds up to over 6 hours travel time. WestJet will supply you with a coffee or tea and a cookie, pretzel or cheese stick packet. Wow! You get to watch fair selection of movies etc on your own phone or tablet - IF you have downloaded the app BEFORE you leave the terminal.Wow! If you need to wait for the bathroom the stewardess tells you to wait in the aisle behind row 3... really? So I can't just stand here in the galley and wait... no sir, behind row 3. Best advice - fly Air Canada - these guys do not deserve your money!"
Pros: "I travelled alone with a baby and all the staff at Westjet wete so helpful"
Pros: "This trip was not full. So I had 3 sits to my self"
Cons: "It was a good fight"

Pros: "Very good"
Pros: "Was first on and got a seat in front on the aisle."
Cons: "The seat was a little tight."
Pros: "Crew was very entertaining."

Pros: "Safe and peaceful flight"
Cons: "A little bit late"
Pros: "Staff was friendly"
Cons: "Just felt to hot and uncomfortable. The seating is to cramped"
Pros: "Boarding was quick and efficient, Crew was nice, competent and friendly. The Flight was quick and uneventful."
Cons: "1. Unexpected 25$ checked baggage fee 2.No meal: They only served drinks, pretzels and hard cookies. Extra food needed to be paid for. 3.Older aircraft so no entertainment options other than TV and Movies. (no way to start, pause or end any movies or programs."
Pros: "Flight and crew were good. Overall no complaints, just preferences..."
Cons: "Food - wish there were more options. Entertainment - I'm not big on downloading an app to watch tv/movies on wifi and feeling exposed using a public wifi. I'd rather it was a tv like JetBlue has on back of seats. Again, not a complaint, just a preference. I was happy with flight...ended up sleeping since no tv, lol."
Pros: "mostly everything that an airline can offer is always on par !"
Cons: "seat sealction - I've booked in advice but seat selection is always a headache. I prefer to have front seats (closes to front in econly class, emergency area) but I got stuck all the way in the back by the washrooms. It would be amazing if on my way back to Calgary I can have a better option?"
Pros: "The crew on the ground and in the air were great and the only positive part of my experience."
Cons: "I was put into the long line to check my luggage with 75 minutes to take off. Of course I missed my direct flight as I was put into a long line. The man who listened to me complain was very kind and empathetic and the only good part about being forced to miss my flight. "We stop loading X amount of minutes before take off" I can't remember the exact number but there was ten minutes to spare before said time when they stopped loading. Dealt with it. Not happy but at least my luggage wasn't lost. Will I fly with WestJet again? Probably. Will I expect some sort of hang up and/or inconvenience? Definitely."
Cons: "Trip from Toronto to NYC should not be so long. Between boarding getting delayed to finding a gate in NY laguardia, it was just extremely exhausting."
Pros: "Quick unload"
Cons: "Big delay"
Cons: "No entertain system"
Pros: "It was quick and efficient"
Pros: "Crew were great..."
Cons: "Food was very poor. Entertainment was awful"
Cons: "Entertainment screen in my seat didn’t work. Old plane."
Cons: "My flight was late arriving in Toronto no fault of mine then the aircanada security took over an hour to get through then they had been paging me and were rude when I finally made it to the plane again not my fault. Did not deserve the attitude!!!"
Pros: "Crew was friendly and helpful on a very full airplane. They did their best to check on connections to let us know if we were going to miss our flights or not."
Cons: "Flight was delayed nearly an hour causing a very tight connection in Calgary."
Cons: "Luggage took forever to get in Halifax"
Cons: "AC was late causing a missed connection to YXE. They were unable to rebook us to Saskatoon for two or three days! They offered standby or Edmonton as our only options. We flew to Edmontonand then drove 6 hours in order to get home for work with no sleep. Unimpressed."
Pros: "Very happy with my trip"
Cons: "My lineup in USA entry line was ridiculous and I missed my boarding time because it was as hard to get the air Canada attendants attention so I ended up waiting 40 minutes anxious about missing my plane. Their kiosks weren’t working proper hence the longer line."
Pros: "I love this flight. Great airplane and great staff. Air Canada international >> air Canada domestic."
Pros: "I was able to change my flight to an earlier one saving me from having to wait 6 hours. I did not have to pay extra for changing my flight."
Pros: "I liked everything. The crew was friendly and attentive and the food was excellent."
Cons: "Gluten free food was mediocre. Worst on any airline. Crew was not attentive and anybrequest felt like an imposition."
Cons: "OK, I get it, so they're not Southwest, I can't get credit on a future flight. But what's the advantage of giving me NO benefit for cancelling? I just didn't show up and they had a surprise empty seat at the last minute. Who wins?"
Cons: "Flight re booked"
Cons: "the entertainment system on this leg of the flight didn't work at all! Give me a break!"
Pros: "the app so you can choose your own movies"
Cons: "very crowded. snacks werent very good or healthy"
Pros: "This was a boring flight which is a good thing, no drama, no mechanical problems, no weather problems. More leg room than an overseas flight."

Pros: "The flight got me to my destination."
Cons: "Cramped seating."
Pros: "Great food, attentive service and comfortable seating"
Pros: "We got there safely."
Cons: "Seats were uncomfortable. Food was simple and bland. I was not allowed more than 2 alcoholic drinks on a 10 hr flight -- what is that?"
Cons: "Flight was delayed by roughly 2 hours allegedly due to construction at the Toronto Pearson airport. I recognize that this was possibly not Air Canada's fault but the delay was still unforeseen."
Pros: "Flight from STL to YYZ was unremarkable, which isn't a bad thing when it comes to air transportation. Bit of a delay leaving, waiting for de-icing trucks to show up and do their work, but I'm not sure that's Air Canada's fault."
Pros: "It was excellent"
Pros: "The app with the movies and tv shows. The non stop flight to Canada. The electronic check in option at the Ontario Airport. The email I received reminding me about the flight The small aircraft on the way from Orlando to Canada The size of the restroom on the plane back from Ontario to Canada. I am pregnant so that extra room to stretch is great. The fast service when retrieving my luggage."
Cons: "My flight back was delayed 2 hours. There were screaming kids on the plane. The flight status on the main screen on the airport reflected a different time than the app."
Pros: "New aircraft 787. Direct flight from Israel to Canada, no layover in Europe. That was nice. The crew was very friendly and helpful. The worst part was the airport in Toronto. Very confusing to get around in. And having to fill out custom papers for Canada when I wasn't staying in Canada or leaving the airport. Didn't like that. But the service of Air Canada makes up for the airport, I would use their service again."
Pros: "I survived the flight"
Cons: "The conditions of the plane were terrible. The plane was old and very cramped with sagging seats so close together I could feel the persons knees behind me. There were no screens for entertainment. The food was horrible, and there was no option to buy anything better. The flight attendants were slow with service and even slower to pick up trash. The 2 bathrooms in the back of the plane were dirty and old."
Pros: "organized crew & good service"
Cons: "there was no check in luggage with the ticket, I have to pay for both my check in luggage while flying back from Toronto to Saskatoon. Atleast one check in luggage should be there."
Pros: "We boarded on time and made connecting flight with no issues."
Cons: "My son had no tv monitor (broken?0 the entire trip with no resolution to the issue. We asked flight crew several times to see what could be done and were told they would reset it. We have very little confidence that was done and no other resolution was pursued. The plane was not very clean and the smell of one of the bathrooms was terrible."
Pros: "Everything was ok."
Pros: "It was short."
Cons: "The gate area was horribly crowded, extremely chaotic and hot."
Cons: "The price was too high for the amount of food you got. The taste could have been better. Wish there were more choices of food."
Pros: "Comfy seats, awesome new movies to watch. Great staff, very helpful"
Cons: "No free snacks, I mean they came around with drinks but you had to pay for all of the food"
Cons: "The system from the beginning was so unorganised ...went 2 hrs earlier even after online check in and it said u need to be there just an hour ..still had to run till the end.. Seat was so uncomfortable ..to add to the agony my luggage didn't arrive and had to wait till evening"
Cons: "Video screen was not working both times. And was charged for check in bag. $25. I didnt get it why i was charged even after paying $510 for a flight. I did web checking for inbound flight n had to pay $25 again. Not happy with that at all."
Pros: "Boarding was pretty smooth and crew was ok."
Cons: "It was very cold in the airplane and if you wanted a blanket you had to pay for it. Also no free food was served. The plane was slightly delayed (~10 minutes)."
Pros: "The staff and service"
Cons: "Movie options from yul to lax"
Pros: "Upgraded unexpectedly"
Pros: "Fairly quick! Staff were really nice and helpful."
Cons: "Flight was delayed one hour. Very uncomfortable seating arrangements for a long-distance flight."
Pros: "the whole process was great. staff at the airport and in flight were all friendly and helpful."
Pros: "I liked the comfort and the service"
Cons: "the long delay in Montreal"
Pros: "We got upgraded into the Elite section, which we excitedly thought would be business class with a nice full recline, as we had been up for more than 24 hours when we left Seoul, but were disappointed. It was more like the Economy Plus on United. A forward cabin with wider seats with a bit more legroom and maybe little bit more recline as a result. On one meal we were served fon china like from business, but on the breakfast, I got china and my husband got the typical plastic and foil square trays. The restroom for the cabin was foreward and was not crowded, which was nice."
Cons: "What I really disliked about the special Elite section was that the arm rests are immovable and the trays embedded in the arms, just like when you are in a bulkhead seat. That's one reason why I avoid the bulkhead seats. So, even though I was sitting next to my husband, it meant that we couldn't remove the 4-6 inches of hard chair arms between us. i could not curl up with my head or feet in his lap, the way we could in a regular economy seat. Therefore I did not sleep on the flight the way I had on the comparable trip outbound."
Pros: "arrived in London."
Cons: "flight delayed from 8 pm to 2 am. $10 voucher for food."
Cons: "Small seat, cold food, main dish was not good, poor selection of movies"
Pros: "no entertainment no food (or to pay snacks , but cannot call that food ) seat designed for kids price average , even not cheap"
Pros: "Plane arrived pretty much on time. Boarding was uneventful."
Cons: "Plane too low to use jetway at Pearson. Epic walk from US gates to immigration. Insufficient leg room if you're over 5'10", but that's how it is these days."
Cons: "First time flying air canada and flight was delayed 1 hour"
Cons: "Too hot in the plane"
Cons: "No free snack offered."
Pros: "Friendly staff today!"
Pros: "This flight offered a small bag of pretzels and a beverage. The movies were new. The crew was friendly."
Cons: "It took us a long time to board because somehow most of the aisle passengers were seated before the window seats, which meant everyone had to get out to let their seating companions on. It provided a fair amount of leg room considering it was an economy flight, but I swear the seats get narrower every time I fly."
Pros: "The crew on board was WONDERFUL. She was so cheerful and clearly loved her job. What a way to end 2015 and start 2016 (didn't get her name)."
Cons: "The plane was very cool but VERY old and loud. Nevertheless, seemed well-maintained and I felt safe."
Pros: "First flight from STL to ORD was amazing. I was upgraded to 1st class...not sure why. Robert was a fantastic flight attendant."
Cons: "There was a delay on my second flight from ord to gsp bc there was some type of miscommunication/altercation with some passengers not wearing masks. I have been traveling since 11 am and it was annoying to have to wait another hour."
Cons: "The internet connection was terrible i was not able to see anything that was being offered"
Pros: "Very good no complaint at all"
Cons: "Not delayed every leg of this trip and extend the travel time from 16 hours to 30 hours!"

Pros: "Efficient crew. It"
Cons: "It was good overall."
Pros: "the fact that the flight arrived on time without delay and the gates were easy to locate."
Cons: "How on earth did my i arrived lagos and only one out of my two bags showed up, i have to extend my stay in lagos and hoping my bag will come the next day, i have to pay $100 extra just to extend my one night hotel booking to two nights."
Pros: "Fast boarding."
Cons: "The flight was half empty and when I tried to move a row ahead of me (from economy to economy plus), the flight attendance rudely told me I had to move back to my seat since the economy plus seat was $70 more. However, a reasonable airline would upgrade their customers to first or economy plus to not only appease their customers but to fill some empty seats. Therefore, I had to spend the entirety of my redeye flights crammed next to someone while I was looking at an almost empty economy plus section. Also, we boarded earlier than expected but we spend an extra hour on the flight waiting to take off. I would not have minded boarding early if we had taken off early, but we took off an hour later."
Pros: "He was the epitome of the Friendly Skies. Chatted with whom wished to chat was quite near those that wanted to snooze on this early morning flight."
Pros: "The crew on the plane was nice and helpful."

Pros: "My wife was happy"
Cons: "Fixing my own supper"
Pros: "Service was excellent"
Pros: "That I didn't have to walk to Fargo. I wasn't dragged off a plane."
Cons: "3 flights to Fargo were cancelled. I was told I would not get to Fargo until 32 hours after my original time I was suppose to land in Fargo. After spending a fair amount of time on the phone with customer service I was able to get me on a Flight to Minneapolis that did not arrive till 1:30am then had to take a rental car to drive 3.5 hours to make it to my destination. I was not compensated for any of this. My return flight from Fargo to St. Louis was also Delayed. Both from Fargo and from Chicago. I have never experienced such poor scheduling from an airline or as many delays or cancelled flights in just a few day period."
Cons: "Never on time"
Pros: "Smooth and positive communication."
Pros: "Everything was smooth"
Pros: "I managed not to use toilet."
Cons: "An epic storm (April 27-May 4) caused my bicycle tour across MO to flood out during our trip. Rescheduling my flight back to CA cost &230..same price as RT. Gouging people leaving a massive flood! The governor of MO declared a State of Emergency yet my trip cancellation insurance didn't cover what was clearly beyond my control. I'm left with some hard feelings."
Cons: "No meal on business, no free internet, no entertainment"
Cons: "Small plane"
Cons: "Flight was delayed so long I missed my connecting flight and spent 18 hours traveling rather than 8."

Cons: "All was perfect"
Pros: "The service was prompt and professional. The plane on this trip was clean and in good repair. The snack was simple and tasty. It was a pleasure flying United."
Cons: "The first flight from St. Louis to Chicago was very small. While I don't have concerns about flying in a small plane, I can imagine those nervous about air travel would feel concerned with the size of the aircraft."
Pros: "Good communication and helpful."
Pros: "The boarding process went smoothly and was on schedule."
Cons: "Overhead compartment filled up and it was hard funding space for my bag."
Cons: "Massive delays on both flights out of O'Hare... No leg room...."
Cons: "Completely missed meeting due to 6 changes made during flight - Ask for a refund of some sort and non was given - not even air-miles or ticket recognition. Customer service from United was almost non existent. Will not be flying with united ever again."
