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..."

Pros: "Everything went smoothly. Flight on time."

Cons: "Original flight was cancelled . Re booked on a different flight , that one was delayed with no new time , with a threat that that flight would be cancelled , we were booked on a 3rd flight , to Toronto to connect to a delta flight to Atlanta . We were told that delta would give us our boarding pass to Atlanta at the delta desk in Toronto. At delta in Toronto we were advised that there were no available seats on the flight we were supposed to be booked on . Delta booked us to Detroit then on to Atlanta . Trip delay was over 9 hours and lots of stress and run around . Very disappointed with west jet . We have always used west jet and this was the first time we felt we were given very poor service .causing a very long and stressful day , arriving at our destination 9 hours later than planned , resulting in a 24 hour exhausting travel day."

Pros: "on time, quick boarding. NO LINES at TSA!!!!"

Pros: "The stewardess serving drinks was very pleasant. Thank You"

Pros: "Easy boarding. The crew helped me with the car seat that was blocked with the seat belt. We got all our luggages in a short time and in good condition."
Cons: "WestJet connect not available on that flight. Bad weather in Montreal (scary landing)."

Cons: "WestJet informed us Kayak did not pay them the funds they took from me on 11/26 and 1 had to pay for full price for the day to fly out. So kayak owes me $500"

Pros: "It is inconvenient to disrupt your plans with such delays"
Cons: "It is inconvenient to disrupt your plans with such delays"

Pros: "The crew and service rendered."

Cons: "It was late. They were waiting on a flight from Toronto so we could board. We board the plan and sat for what seemed like a very long time. We were not even offered a glass of water on the flight."

Cons: "The chairs were in bad condition and the airline was delayed which made me nearly miss my next flight."

Pros: "No issues"

Pros: "Everything went as expected and on time."

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

Pros: "Everything except the delays. I like the new app on your phone or tablet to watch movies and TV (and it's free now to watch movies like on AC!). I approve of this change westjet. The staff are very good at informing customers to make sure they download the app before boarding. However because people generally suck and don't listen there is always someone complaining about not having the app on board afterwards."
Cons: "Unfortunately this flight number is always delayed, WS269 Friday YHZ to YYZ. This is the flight I always pick for work schedule compatibility, but have found it to be delayed 30 min to 2 hrs the last 4 times I've taken it in the last 3 months."

Pros: "The airline attendants were very friendly"

Pros: "On time"

Pros: "Helpful staff"

Pros: "The crew was very nice and accommodating. Boarding was well organized and fast."
Cons: "No food and very warm on the plane."

Pros: "Nothing in particular."
Cons: "We were delayed by 30 mins. We waited another 20 mins at the gate because there was another plane there. We only got cheetos as a snack."

Pros: "Crew was friendly and helpful. Inflight internet was a great plus."
Cons: "Nil"

Pros: "A few days before our flight to Halifax which was originally scheduled with a stop over in Toronto, we received an email from Westjet that they were putting us on the direct flight. This enabled us to avoid the Toronto bottleneck and get to our destination on time. Thank you Westjet."

Cons: "Air Canada needs to update it's entertainment systems. On flights to and from my destination both the audio jack and screen were broken. Also, the flight did not receive any salads, leaving this vegan with slim pickings. Get it together, Air Canada!"

Pros: "Staff are very nice"
Cons: "Delay in flight of more than 45 minutes"

Pros: "Boarding was good and fast"
Cons: "The audio jack was not good thus I had to keep it steady with my hand to be able to listen to movie"

Cons: "The delay was ridiculous. Seats are the usual tiny ones so for a big guy they suck but over all great trip"

Cons: "My flight was an early morning flight 8 am. I needed to get up at 5 am to get ready for this flight. AC notified me 5:05 am that my flight delayed 3 hrs to 11am. I wish they told us the night before so no need to get up that early."

Pros: "Got the seats I wanted, movies were good. Staff was friendly"
Cons: "In Montreal they took my carry on bag stating it was too big, I have traveled with it many many times and it always fits except the tiny planes, this was a 787. When I got on the plane many people had larger bags then mine and it was the last bag on the carousel at the other end."

Cons: "We had a 5:35 am flight and the plane was 1/2 hour late to gate. By the time it got there, we spent over 1 hour sitting at gate loaded up waiting for weather to clear. It was fine when it was supposed to be there. Therefore, this was not initially a weather issue. Our connecting flight is 12 hours after Our schedules flight. I have a 1 year old toddler. Customer service rep less than sympathetic personality."

Pros: "Nothing much"
Cons: "Please train this guys for customer service and fix there attitude."

Pros: "Entertainment system was good and seats were comfortable"
Cons: "Boarding was confusing because there were few or no announcements of which zone was boarding, and it wasn't clear exactly which desk to proceed to for boarding"

Cons: "Dirty plane, garbage stuffed in seat pocket. Tray table disgusting!"

Pros: "Nice flight"

Pros: "Smooth as you like"

Pros: "Very organized crew for the boarding on instructing passengers with carry-ons etc for the overhead storage compartments. Flight left on time."
Cons: "My entertainment screen was malfunctioning. Very frustrating trying to watch a movie to the point I turned it off & read a book . If you are going to offer the the service make sure it works."

Pros: "The tvs were nice."
Cons: "The people in front of us reclined their seats and there was no leg room. The flight was severely delayed by an hour and a half making us miss our connection."

Pros: "Great service"
Cons: "Not enough time to the flight from Halifax to west plam beach"

Pros: "Everything went very smoothly with this flight. It boarded on time. The crew were all very friendly. I enjoyed the entertainment selections and found a tv show that I had been wanting to see. I managed to watch 2 episodes and look forward to watching more of the same show on my flight back. I ended up having the 2 seats to myself which was great. Extra legroom. I have no complaints at all."

Pros: "Exiting the plane and terminating my transaction."
Cons: "Delayed. Missed layover. Lost luggage. Poor communication. Agents had attitudes."

Pros: "On time"

Pros: "Air Canada couldn’t have been better, I missed a flight they waived their fees and got me on the next direct flight home. Wonderful service !!"

Cons: "Delayed"

Pros: "Boarding process."
Cons: "NA"

Pros: "On time"

Pros: "Airline provided a flight to Toronto, with reasonable amenities and boarding process."
Cons: "Had to load my own suitcase on the luggage belt - I am elderly, with back issues, traveling alone. Attendant was courteous and helped me, but stated that staff "doesn't do it any more" because of safety issues. No help will be given in the future. Plane left two hours late - I missed my connection. Was given a stipend for an overnight stay, but no explanation was given about the delay. Staff couldn't tell me if my checked baggage was on the plane the next morning. I probably won't fly Air Canada again."

Pros: "On time"

Cons: "Almost 2 hour delay in Halifax until 1:30 am but Air Canada lounge closed at 11 anyway."

Pros: "Good breakfast."
Cons: "Cabin was cool"

Cons: "It was 3am and my boarding pass wasn't bright enough on my phone. Instead of politely asking me to go print out my boarding pass at the check in stations, she yelled at me and told me I was holding up the line"

Cons: "Flight was delayed 1.5 hours but no one was in much of a rush to get it going"

Pros: "The smooth take off & landing"

Cons: "Too hot and cramped"

Cons: "Kayak did not allow us to reserve seats, and the seats we received were not together, even though we purchased the seats six months in advance. My seat was at the front facing rear wards, with a non-tilting seat and little foot room."

Pros: "Seating in a double rather than triple layout."
Cons: "Delay of almost an hour on the runway because of a mechanical problem, after being asked to turn off cell phones and so we couldn't notify those meeting us. Our flight arrival did not appear on the board at Pearson , thus complicating our communication with those meeting us. Baggage was slow being unloaded. Will seriously consider flying to Hamilton with West Jet next time we return from Halifax."

Cons: "Air Canada shares a trait with many other incompetent organizers: everything is fine if nothing goes wrong, but there are no contingency plans in place in case something goes wrong. So, things get more and more delayed. Can't you predict roughly when the plane is going to land (once it is in the air!) and arrange for some gate to be open, so that we don't have to sit on the ground for 45 minutes once it has landed, for example? People who know how to organize are ordinarily capable of doing that. Furthermore, the lack of transparency is really frustrating: we just sit on the tarmac with no indication of how long we're going to be there, and the estimates of the delays are completely wrong when we're given them."

Cons: "Lousy food and no snacks"

Cons: "Our flight originating in Halifax was 1.5 hours delayed and we knew there was no way we would make our connecting flight in Toronto with a 40 min window to pass through customs, US immigration, and reenter security into the US bound F gates. We requested to be rebooked for early the following day to avoid being stranded in Toronto. Acknowledging it was unlikely we could make the connection, the staff told us that because the computer didn't list it as a "missed connection", they could not take any steps to rebook us. Of course, we missed the connection and were stranded for an entire 24 hours in Toronto with two small children."

Pros: "This was my third air canada rouge flight so I knew what to expect. Staff are always super courteous and good food options available."
Cons: "Almost 0 arm/leg room, flight was delayed and they tried bumping me off my flight onto another because they had overbooked."

Pros: "A very typical flight."
Cons: "No complaints."

Pros: "Flight was only half full. It was a red eye from Halifax to London, so there were several rows with no one in it. That allowed me to move to a row that I could lay down in. Flight attendants were pleasant. Everything was included (ie, food, free checked bags, earphones for TV) Great value for money."
Cons: "I watched WTF on the in seat entertainment system but it was not formatted for that screen, it was too narrow and the sides were cut off so part of the action was not on screen. Pretty minor issue."

Cons: "The security check took so long. We made it last minute even thought we were in the airport more than 1.5 hours before the flight (as recommended)!!"

Pros: "flight was fine pleasant flight attendants was late flight so slept a lot now much to add"

Pros: "The t flight was completely uneventful-the best kind."

Pros: "Crew was fine, should serve at least a cookie with the drink..."
Cons: "Didn,t like the service I received getting off the plane.. Cannot walk any distance..Didn,t order a wheelchair, because I didn,t know I had too. Asked for a ride on the golf carts, got told to walk around the corner, and one will pick me up!! Never saw one yet!!! Took awhile but managed to walk to the luggage, but had to sit for half hour with the pain in my legs.....No thank you Air Canada, next tine it will be different air lines....."

Cons: "Our flight from Halifax to Los Angeles via Toronto should have left at 3:15 on Sunday so that we could arrive back in Los Angeles by 10:14 pm. Instead the flight was delayed and left 200 people stranded and waiting in line for customer service. Because I did not have cell service in Canada, I was forced to wait 2 hours in line only to have the agent at the counter make me talk to an agent on the phone. Prior to that, we were shocked that one of the only two agents at the counter left the counter to talk to people in line behind us instead of servicing the customers first come first serve. When I asked him to please return to the counter to help the next person in line, he mumbled that that was not what he wished to do. Meanwhile, all flights out of Toronto were fully booked that night. The delayed flight finally left at 1:30 am. Had Air Canada notified its customers about the 10 hour delay, we could have spent that time in Halifax. Both my husband and I were very disappointed in how AC handled the whole situation. Both the counter agents and the phone agent were unhelpful in offering us options."

Pros: "when I landed"
Cons: "First off the the plane was mid takeoff and stopped which terrified the passengers and crew. Then we learned the plane had technical issues which lead to a 50 minute delay, then air canada did nothing as in terms of compensation. My audio jack for the entertainment system was broken, seat 19F on flight 617 by the way... Then I got up to use the washroom and when I came out I had to wait 30 minutes at the back of the plane standing until the servers were done serving drinks and snacks/food. Then the landing was terrifying as the plane was swooping/shaking much more than normal, even the board crew looked a bit worried. Could NOT wait to be done of the flight, one of my worst ever."

Pros: "Very satisfied with the flight."

Pros: "Worst service I've ever had"
Cons: "The flight for Montreal was half empty and than there was a flight to Toronto Hallf empty as well, and the flight Toronto to Montreal was half empty...by coincidence our flight Halifax-Montreal on Sunday at 19:15 was cancelled due to technical issues. However it was obvious that AirCanada didn't care about the passenger time or valued it...instead of flying 3 empty flights they cancelled our flight and maximize capacity on the other planes...not happy we didn't get any voucher and we wasted 4 hours of our time and didn't have dinner until 1 am"

Pros: "Staff and plane were fabulous"

Cons: "This site allowed me to book a CANCELED flight. I found out 20 hours before my scheduled flight that I was on an 11:20pm flight not a 7pm flight."

Pros: "Good service...plane clean....attendants very attentive to all passengers!"

Pros: "Everything went very smoothly, no delays, good staff, all good :)"
