Airline reviews

Cons: "I find the planes are far to compact and its really hard if you have a long flight. The body becomes stiff and really sore from not being able to move about much."

Cons: "Because of Boeing disaster did not go to Halifax but were sent by Westjet to TO and then on with Air France. Boarding areas in TO are a long way away (lot of walking) and customs in TO is frustrating and takes a long time."

Pros: "Pleasant staff"
Cons: "People get shocked from the rush of air soon after they board and close their air knobs overhead. The cabin was filled with lots of new bodies that had different ordour and perfume that it was good to have a strong ventilation but due to the strong air flow... Perhaps tell ppl to keep it open."

Pros: "The food was good and the crew were friendly."
Cons: "We could have used more legroom between the seats."

Pros: "Great crew, very accommodating for a small and short flight"

Cons: "Total rip off. I won't be flying West Jet again if it can be avoided"

Pros: "Crew was great. I was able to watch my favourite CBC shows due to the screen on the seat in front."
Cons: "Nothing really, I paid $500 for the return flight and feel I got fair value for the cost."

Pros: "Amazing crew. Brand new plane."

Cons: "More water and a tv like air Canada"

Pros: "Entertainment was excellent"
Cons: "The airport staff was horrendous."

Pros: "noone booked in the seat beside me allowed for more room."
Cons: "food (ran out of items I wanted) seats are mediocre no entertainment stewardess forgot my cream for the coffee - too busy chatting with another passenger."

Pros: "Friendly crew"
Cons: "That westjet q400 is an awful aircraft with terrible slimline seats"

Pros: "Flight was on time and WJ does provide quite a lot of leg room on their jets."

Pros: "The ease of boarding with very nice staff!"

Pros: "The staff are friendly and efficient"
Cons: "The plane is cramped and a noisey propeller model."

Pros: "The friendliness, the options through the app with movies etc"

Cons: "Need more leg room on board"

Pros: "This leg of the travelling was fine. I know I got fleeced on the price of the round trip to go home for a funeral but didn't realize just how bad until my seatmate told me he paid a third of what I did. Note to self: Don't ask the traveller next to you how much they paid for their ticket..."

Cons: "No in flight entertainment unless you download their app, however there was no signs or announcements to warn passengers of this. Flight was delayed and they lost my baggage even though it was a direct flight. Not impressed."

Pros: "I went through customs and then walked via escalators and moving walk ways to b4. It took me almost a hour. I was the last to board I am sure And had to collect my own luggage and take it from one point to another. I am 70. thank god, when I got on the plane I sat in 3a and was offered a free glass of wine. halleluya. I was exhausted Toronto airport is always a nightmare. I travel a lot and will avoid this airport if I can. I do like West jet but Delta /west jet connection means I have to take my bag from one place to another and I walked miles and could have missed my flight. I am tired. I am going to bed"

Pros: "Korean air is very efficient."
Cons: "We had to rent a car to get to Ottawa because West Jet had cancelled all their flights due to weather. All Air Canada flights were operating. We waited in line for 2 hours at the airport for West Jet to tell us that we needed to call them regarding a refund. We called them and were on hold for an hour and 45 minutes. Then we were told we had to call the travel agent...we on hold for 2 hours. We then called Korean air and they told us they couldn’t contact West Jet-no one knew what the value of the flight from Toronto to Ottawa was. We were only provided with a refund of $4 (for the taxes) when it cost us $280 to rent a car to get to Ottawa. I will never book a flight with West Jet again."

Cons: "Boarding outside with no notice or warning"

Cons: "Our hour-long flight home from Toronto to Ottawa was delayed by two days. WestJet provided a hotel voucher and food vouchers for one day but refused to refund us for a car rental that would get us home in time. While we made our own way home, we were emailed to say that our flight home was delayed twice more."

Pros: "Very disciplined and hard-working crew did their best to keep everything under control and moving on schedule. Boarding was busy but fairly well organized considering."
Cons: "Flight had an abundance of minors and babies at no fault of anyone, just unfortunate. Lots of crying, screaming, fidgeting and puking. Customers were pretty impatient in the early morning as well which didn't help the situation. Not sure if snacks or refreshments (other than water) we're handed out in a 4.5 hour flight as well."

Pros: "I liked the friendliness of the crew and how accommodating they were of me and of their guests!"
Cons: "There was quite a delay on my flight and I didn’t get an email to let me know there was a delay. Because I happened to go to check in earlier, I happened to noticed the delay. I wasn’t happy about not getting an email. I called West Jet to find out about the delay and it took approximately an hour to speak to someone. When I did, the delay was explained as weather related and the reason for not getting an email was because they hadn’t gotten to it yet I believe. I wasn’t happy with that as a reply. The flight was then delayed again by several minutes. I would have appreciated some form of compensation as I was going to get a lift home from the airport and ended up having to pay for a taxi as I was coming in so late. In all other flights, I know west jet to be quite an accommodating airline. The crew was great, I simply didn’t appreciate how the delay was handled."

Pros: "Got a window seat Good deal on price from kayak"
Cons: "Delayed by 2 hrs Lost my luggage and no word on when it will be returned Never told us about why delayed"

Cons: "Didn't fly on the day I was supposed to fly due to delays. I had to figure out for myself that I wasn't going to make my connection and thus I went back home. We agreed to itinerary for the next day that had a 2+ hour wait at la Guardia and yet I still almost missed the N.Y. to Tampa flight due to delays out of toronto. Had to sprint from one terminal to the other. In Toronto we sat on the tarmac for 90 mins, and this was after dealing with security and other issues with checkin before i even got on the plane. For example, it was difficult to explain that i had already paid for my checked bag the day before. As a result I never got a chance to eat the entire day. And then my bag didn't get to Tampa until later that night anyways. Although the individual staff members were all very nice, there were institutional flaws that made two days very frustrating. I have some sort of debilitating delay on more than half my flights over the last few years, and rarely is there ever an explanation or compensation."

Cons: "It was delayed."

Pros: "Kayak was great to book through. Very simple. Plane ride there was great."
Cons: "Plane ride home wasn't good due to the airplane propellers being louder then usual and noisy, a little unsettling."

Pros: "Friendly people+ great service"

Pros: "It was on time. Quick to board."
Cons: "I’m used to entertainment."

Pros: "Friendly crew"
Cons: "Entertainment selection is lacking."

Pros: "Quick, efficient and funny friendly staff"

Cons: "Delays Boarding: boarding from both doors: back door and front door, but no direction from the crew to anyone. Ended up with passengers trying to get in the front from the back and passengers trying to get to the back from the front. This created another extra 15 minutes delay when everyone were stuck in the middle...The rest of the passengers waited outside in Canadian winter cold. On a flight already late."

Pros: "Short flight"
Cons: "Nothing"

Pros: "I like that I got the plus seat for no extra charge."

Pros: "Flight attendants were polite and helpful."
Cons: "Multiple delays totalling up to 2.5 hours but only updated 15 minutes as it reached the time of take off. Minimal heads up prior"

Pros: "The airline attendants were very friendly"

Pros: "Flight staff"
Cons: "Had to disembark. So left and arrived much later than planned."

Pros: "Crew were all very welcoming and polite"
Cons: "Food and entertainment were pretty pricey."

Cons: "Our flight was delayed. However it was not really within their control."

Cons: "They automatically gave me the window seat"

Pros: "Bell's live TV is probably the best feature!"

Pros: "Always on time and arrived early"
Cons: "Better snacks like porter"

Cons: "No entertain system"

Cons: "Same comment as the previous flight ref movies. I wont take Westjet again on a long flight without movie screens. Not all old people have Iphones or laptop computers. Mike C."

Pros: "The gate and air crew were very friendly. Flight right on time."
Cons: "Not much legroom."

Pros: "Great service! Crew was very friendly and happy. Flight was online and landed early"

Pros: "Poor"
Cons: "Luggage did not arrive in Pisa. No big concern expressed or info given in support of what I could spend to get essentials. Poor communication. Need an English speaking BA employee to sort these messes out. My luggage was to go from Londod ON Canada to Toronto Canada to Heathrow UK to Pisa. Made call in evening and part of info I had given at airport as to my hotels to receive luggage when found was not communicated in the computer.Luckily I called."

Cons: "Extra rules about headphones are annoying and no beverage options. Horrible terminal that does not let you get a drink before boarding and gate agent did not update boarding when it was late, so no one could venture off and get a drink of water before flight."

Cons: "Late. Wifi on the aircraft but didn’t work. Inflation GHY service suspended due to reported turbulence."

Pros: "The seat beside me was vacant, so I had extra room."
Cons: "Flights in the late evening from Toronto to Ottawa always seem to be delayed. We spent a lot of time boarding, and a lot of time de-icing before take off. There would have been plenty of time to serve refreshments during de-icing. But refreshments and dismemberment of ear phones only began once the plane was airborne. There was not enough time to service all the passengers at that point. I'm not sure why Air Canada cannot at least give you ear phones when boarding. And why cannot refreshments be served during de-icing?"

Pros: "The fact that the in-flight meal was as cold as the crew, and you got to pay for that coldness. Just love it! You get me right?"
Cons: "The Montreal-Vancouver route was by far the worst. The attitude of the crew was denigrating and arrogant."

Cons: "Had to spend the night in Toronto for flight delay"

Cons: "N/c"

Pros: "Everything, good food, good people, good times"

Cons: "They lost our checked baggage. Luckily we did get them back within 20 hours."

Pros: "Seats were pretty comfy, snack provided even though the flight was short"
Cons: "Cabin could have been a little cleaner before boarding"

Pros: "good overall...so MUCH BETTER THAN Air Canada rouge service we took from Ottawa to Venice. Rouge service is very poor!!"

Pros: "The pilot and the crew are very proffesional."

Pros: "Everything on time"
Cons: "Nothing"

Pros: "Cleanliness, crew (in general)."
Cons: "Problems with entertainment system sound seem to be a recurring problem aboard aircrafts - the jacks seem to be in bad shape in most, whether for the provided eraphones or those brought on board."

Cons: "AC was helpful arranging a delivery of the delayed luggage. But carrier was further delayed from the scheduled delivery time."

Pros: "Airbus 380"

Pros: "We had lots of leg room unlike the Air Canada Rouge flight that we took from Toronto ON to Kelowna BC. Also very little table on the rouge flight."

Pros: "Service was poor. Attitude was less than enthusiastic."

Pros: "Nothing"
Cons: "Cancelling flights , lying about reasons why, running away from customers when the flight finally after 10 hours was canceled"

Cons: "The staff was really nice. However I was asked to switch seats and a flight attendant spilled water over me. They were very thankful that moved and very apologetic about the water so I feel bad for bashing them, I just think I should have gotten a free snack or something. The rest of the flight was alright."

Cons: "In order to make more money, Air Canada purposefully sits couples, families etc. who book together separately, in order to try to get them to buy upgraded seats together."

Pros: "Entertainment system did not work"
Cons: "Crew provided a card to contact air Canada for compensation"

Pros: "Leg room adequite."
Cons: "Only beverages served, there wasn't the usual snack."

Pros: "Seat availability (lots of empty seats) Entertainment system had lots of movies & music Friendly flight attendants"
Cons: "Flight attendants could be more aware of his/her surroundings. For example, I was either stepped on (as a result, being woken up) or my backpack was stepped on several times when an attendant was walking down the aisle, and neither of those things were sticking out into the aisle. This has rarely happened to me on trans-Pacific flights (more crowded, longer flights) so I can only attribute it to the carelessness of the attendants and/or the aisle width but since I think aisle width follows international standards it's more likely the former."

Pros: "Not refunds, no voucher, no credits .... But still s stupid fee of U.S 200 to pay on my Next flight using same booking Code . RIDICULOUS !! Guess other airlines want my business and my friends' too.."

Pros: "It was great"
Cons: "My "window" seat was beside a wall. So i actually didn't even have a wi dow seat, not really."

Pros: "They were able to put me on standby for the next flight and I made it on. I would have been upset if had to wait for the last flight at 10:55pm. I understand this is not always in the airports control."
Cons: "My flight from Montreal to Ottawa was canceled and I almost had a panic attack. I was flying alone for the first time."

Cons: "Movies and audio lacked currency, simply old and little variety."

Cons: "No good movies or music"

Pros: "I arrived early and was able to change my flight to an earlier one."
Cons: "The air hostess/stewardess was surly...and looked like she hadn't slept.."

Pros: "Leg room was great."
Cons: "The pilot wasn't that good. It wasn't a smooth landing at all."

Pros: "We left and arrived early, the seat was surprisingly comfortable (it helped that there were lots of empty seats, including next to me), my full-size carry-on fit easily in the overhead bin, despite it being a small plane, the in-flight entertainment was always on and pretty good... everything went well."
Cons: "Only the things I've grown to expect on any domestic service (e.g., no food)."

Pros: "Great service on a quick flight"

Cons: "There was no access to movies."

Pros: "I like the comfort of the seats and how fast the boarding and take off was."
Cons: "I did not like that I was not offered peanuts during my flight. The last time they offered free peanuts"

Pros: "as above"
Cons: "nothing"

Pros: "Space and meals"
Cons: "Entainment"

Pros: "The fact that I was rebooked immediately to my new flight AC-DC 705 at 8:50 am by two wonderful ladies at La guardia airport who comforted then boarded me unto a flight due to the fact that I missed my original flight. This occured due to the Airport being Unorganized! As I had checked in well before 3 hours and was on time for my original flight at 8:30 am."
Cons: "The airport was extremely packed, Unorganized and not well staffed. What I hated is that when I arrived at my original gate A7 the gentleman who boarded my original flight was unprofessional, rude, basically ignored me and said "You missed your flight !" Not even taking the time to listen to my situation or guide me in my next steps of acquiring a new flight to go to my classes and home in Toronto!"

Pros: "Comfortable and large plane with tvs"

Pros: "Everything but the size of the in-flight seats"
Cons: "Seats way too small and uncomfortable."

Pros: "On the plus side, the service was great."
Cons: "There is just not enough space in the seats! I am not a tiny person and my trip was not helped by the fact that the seats are too narrow to comfortably seat people larger than a size 10!"

Pros: "The plane was fairly modern and the seating had more leg room than many other economy flights I have taken. The flight attendants were friendly and courteous. All-in-all a very good flight. I was especially appreciative of the concessions made for skiers when it came to luggage. Also, the luggage fees were very reasonable."
Cons: "I was a bit surprised that no snacks were offered free of charge. I can understand that meals are not included in economy, but nuts, cookies or some pretzels would be nice."

Pros: "AC changed to a different plane for our flight at the last minute, so seat assignments were messed up, and we had paid extra to choose seats. So why pay extra for seating when the airline can put you wherever they want at their discretion. In addition there was a minor delay in take off while the flight deck crew had to re-programmed the avionics to our scheduled route. But we made up the time en route and were only a few minutes late. On the whole, not a bad flight experience, just the usual frustration in the process. I long for the days when flying was a pure pleasure."

Pros: "Hourly flights in a Boing 676. Comfy economy class seats with leather headrest (cleaner than fabric). Ample overhead space for carry ons. Individual TV monitors with entertainment (I prefer leaving it on flight itinerary status while reading a book). Good bretzels & tomato juice served by a multilingual flight staff. Boarding, departure & arrival on time to the second. Can't ask for more."

Pros: "the short flight"
Cons: "the comfort and location of seats ran around for days acquiring a doctors note for easy access seating. grateful for the refund but would've rather paid and actually been accommodated."

Pros: "Flight attendant very caring and friendly."
Cons: "Gate attendant very rude - made my daughter cry Her seat was way at the back. Baggage handlers lost a luggage strap - sturdy one 7 boarding pass The gate was changed to one at the end farthest from original gate It was supposed to be two flights - she ended up with 7 boarding passes in the end. Second really unpleasant flight with Air Canada in less than a year. Will avoid Air Canada from here on."

Cons: "Salty pretzels!"

Pros: "flight was on time"
Cons: "not even a little snack served with the drinks and the amount of legroom was minimal and I'm not tall"

Pros: "The crew actually enforced the zones when boarding, which often isn't the case and tends to slow things down."
Cons: "This connecting flight was worse, as we sat on the tarmac for well over an hour and were not provided with so much as a single beverage the entire time we were waiting or flying. Apart from the great in-flight entertainment system, the whole experience was brutal."

Pros: "Crew are very friendly and boarding was a breeze."
Cons: "For the huge amount of money they charge us for national flight with no included meals or even snacks its ridiculous!!"

Cons: "Ticketed for Air Canada, but it was a code share flight with United Airlines. The check in at United took over 15 minutes because my reservation was not recognized by the United online system. Luckily a United agent was able to work through my paperwork and get me checked in, with luggage, via Ottawa to London, Heathrow. However, at the boarding gate for my flight to Ottawa, my boarding pass was deemed invalid and it took another 15 minutes to issue a new boarding pass - with seating at the back of the bus. Was a frustrating/annoying process. Luckily I encountered two capable United employees who worked to resolve the issues."
