Pros: "There was enough leg room and boarding was done reasonably quickly."
Cons: "The flight was delayed by 15 minutes without explanation."
Cons: "The flight itself was great but it was very late in starting due to technical problems with the aircraft."
Pros: "IFE, good system, GUI, and good content, various options and languages."
Cons: "Crew service, uninterested, careless, unemphatic, absolutely not dedicated to service, even borderline rude."
Cons: "BOTH OF MY CHECKED IN LUGGAGE WERE LOST"
Pros: "The crew was kind"
Cons: "Seat space is too cramped"
Pros: "Comfortable and a very friendly flight crew."
Cons: "Terrible layover in Vancouver. There was not need to make us leave the plan for 3 hours and get back on the same plan"
Cons: "Not enough washrooms for # of people. Denied us of from WR. Food carts blocked WR access to most people for long periods of time."
Cons: "The seats have to be the most uncomfortable I have ever had a chance to use. They were uncomfortable from the get go, so it is not just the length of the flight. The general cleanliness was also an issue."
Cons: "No potable water on board meant no tea or coffee."
Pros: "Captain kept us in a loop. Great crew."
Cons: "Boarding was a mess. I really wish A/C would implement some sensible system. Had to delay departure to unload someone's bag. We made up the time only to loop around LHR for 25min."
Pros: "Entertainment system is better than usual"
Cons: "No wifi available for purchase for such a long flight"
Pros: "The attendants were very helpful and everything was orderly. For the price it was a very good flight."
Cons: "No individual entertainment on an eight hour flight."
Pros: "Crew was great! Seats small and terrible !"
Pros: "The boarding and deboarding of the plane were done quickly."
Cons: "The flight was delayed 4 hours and the entertainment selection was subpar."
Pros: "On time"
Cons: "Seats the the very rear"
Pros: "Friendly staff, happy to help"
Cons: "Terrible food, plane was overbooked, they only offer 'in-ear' headphones, they have squeezed maximum seats into this plane to increase their profit. Would absolutely NEVER fly Air Canada long haul economy or premium economy again."
Pros: "The seats were large, and they had power."
Cons: "The flights were both 2-3 hours late, and the airplanes were dirty. They blamed it all on weather, which is fair, but it's almost like their attitude was "hey, we're leaving late already (arriving at 3 am at my final destination), so we might as well not try to have good service since you'll already have a bad memory of this flight!" That being said, I would still take Air Canada in cases such as these where they are $400 cheaper than the competition. I'd still rather have a terrible flight and save $400 at this point in my life!"
Cons: "This is my 4th time getting my flight cancelled with air Canada for no apparent reason. The food was horrible and the service was worse. Never again."
Pros: "The exact timing going and coming"
Cons: "After returning back and the airplane taxing on the ground it takes one hour to go out of the airport gate to my riding although I have no luggage"
Cons: "Why don't you give away cookies too?"
Cons: "There was only one staff working at the gate, and one family with kids seemed somehow stuck with their documents. This kept all other passengers,who had already Lined up, waiting for quite a while. Some people grew impatient."
Pros: "The agent at check-in was very friendly and helpful."
Cons: "Flight was delayed, so missed connection. As it turns out, Air Canada was aware all along that we would miss our connection; however, they still had us board. The gate agent should have been conscientious and informed us that the delay was ongoing with our flight being number 22+ on the tarmac to take off, thus guaranteeing our missed connection. They should have rebooked us on another flight from our original destination vs rebooking us upon arrival in Montreal to miss further connecting flights. Very disappointed!!!!! Based on this experience alone, never again will I or my family travel Air Canada."
Pros: "Everything went smoothly & everyone was helpful"
Cons: "Nothing every thing went well"
Pros: "Pretty much nothing, this goddamn company has so little to compensate for the great inconvenience they provide in mismanaging our flights."
Cons: "I was delayed significantly for both flights on my round-trip and all Air Canada can offer is 15% off my next flight with them. What an embarrassment this company is to be the official airline of Canada. They should change their name to Air Rouge and allow some other company earn Canada in the name. What absolute trash honestly, if you like delays because the plane has a technical problem and they can't even sort out a back up plane within 6 hours, at their headquarters with all these hangers and planes at their disposal, then at least you'll get 15% off your next delayed flight with them."
Pros: "Great food, comfortable seats."
Cons: "Long delay on departure, the ground crew decided to leave without clearing us for the flight. Probably helped cause the luggage catastrophe that followed on the next flight."
Pros: "Excellent service, good food, business class on the 787 is very nice."
Cons: "Nothing"
Pros: "Reasonably good all around."
Cons: "I paid for an upgraded seat on this flight and wished I hadn't. Whole rows of seats were empty and I would have been more comfortable in my original seating, according to the seating plan during online check in the entire plane was booked out but for a few seats."
Cons: "Many of us were refused boarding on the connecting flight. They gave away our seats. I arrived at the transvfer counter50 minutes prior to the flight. I was first. Gave excuse that bag must go with me. Customs confirmed that this is AC not customs. To add insult, they flight to Montreal was late, the flight to Boston was late, and finally my bag NEVER was on either flight so there excuse was an out right lie. I missed half the weekend home in over a month. AC doesn't value my time and I don't value their service. Every time I go back to this airline I realized why I left. Going to Asia; don't get suckered into using this route. BTW a friend on PVG-YUL-BOS never made it as well. AC still using a CRJ200 that can't land in weather. NOT A BUSINESS CLASS EXPERIENCE."
Pros: "Our flight went by quickly, as the seats in Economy were very comfortable and the crew was very kind and accommodating. There was a great selection of movies and TV on the individual entertainment screens. We would definitely fly Air Canada again."
Cons: "Nothing- one of our best international flights!"
Pros: "There were a couple guys sitting behind us who kept asking the stewardesses for more beer and more wine. And the stewardesses kept giving them for what they asked (free). These guys became loud - as drunks do. It was annoying as we couldn't hear the movie we were watching because those guys were so loud. Any alcohol being served out of meal time either should be charged or put a limit of two max."
Pros: "Would have liked something other than pretzels."
Cons: "I called customer service to ask questions about the meal options, and for both flights (14.5 hrs) they signed me up for the wrong meals! The staff on the first flight was extremely rude and unhelpful, and refused to let me eat any of the extra meals. Making matters worse, I had asked customer service when I called if they sell food on the flight, which I was told yes. This turned out to be untrue. I had to survive the 14.5 hour flight by only eating 3 tiny bags of pretzels. I sent an email to customer service to complain about this (can't do this over the phone), and didn't hear back for more than a month. On my return international flight, I was AGAIN signed up for the wrong meal (vegan) even though I specifically went over my dietary preference (vegetarian, eats eggs and dairy). Then my luggage was left in Vancouver while I made my way to Sydney, so I had to wear the same clothes for over 72 hrs while the airline "apologized" with giving me only $50. I finally got someone to respond to my complaints when I tweeted them, and their response was that I selected the vegan food option...NOPE, and that's not an apology. I will not fly them again. (PS: they don't give eye masks or toothbrush/toothpaste on international flights even though other airlines do, and their selection of movies/TV shows is about half of other airlines)"
Pros: "screen and interface"
Cons: "back of seat/head rest uncomfortable, average food in very small quantities films not refreshed fast enough, same in and out flights"
Pros: "Crew was lovely. Boarding flight was easier as we were alou d to go on first with small child"
Cons: "Not a lot of space on flight. The food could be improved."
Pros: "Good flight once we got on board."
Cons: "Plane was about an hour late taking off, seems the maintenance guy lives 45 minutes from the airport and we all had to wait on him to get there to look at a paint chip on the nose, which took about a minute. They might want to have someone on hand."
Cons: "Flight was delayed for 45 mins. The Toronto Airport Terminal B was hellascious. No AC. Then we had to turn around after we were half way to Nashville and change planes. Not a good way to end a great trip back from Europe."
Cons: "I attempted to check in three times the day before online- only to be told that there was an error of some sort- and to check in upon arrival. Although our arriving flight arrived over an hour before the Scheduled departure time- yet we were told that the flight had been closed. Despite the fact that she could see my name and my husbands name on the screen for the flight. We informed her that we had attempted to check in online three times but we're not allowed to. I believe it had something to do with checked baggage. After demanding to speak to someone in charge- we were told that the airport supervisor needed to be told by air canada directly to reopen the flight to allow us on. At this time my husband has been on hold ( an international call- seeing as we were on an island) for nearly 30 minutes- finially someone picked up and essentially told us that there was no way for air canada to do that and in fact it was the arriving airline that we should be communucating with. At this point- we hung up. Fearing that we would be stuck there- although the plane had still not departed- but since the supervisor of the airport never physically appeared so that we could discuss the issue in person- I went to another airline , American, to try to find and pay for, mind you, another way to get my husband and myself home. After spending another $1500 to do so- we boarded the American flight and actually made it home before our scheduled time had we been allowed to board the air canada flight. Honestly- I'm not sure if it was air canada or the airport... But I do know that my husband and I will never fly air canada or honestly- I have no desire to go back to the airport where this incident happened- which is sad because I like to contribute to the tourism economy of small island countries... But this one is no longer in my list."
Pros: "Clean, prompt, attentive staff"
Pros: "- On-time departure, attentive staff and good selection of entertainment to pass 5 hours of travel time - Love the pre-boarding for families with kids - Good overheard space for carry-on bags - flight was not way overbooked and no one had to scramble for space"
Cons: "- Narrow leg room - relaxing in the economy class was challenging (but not surprising experience)"
Pros: "I honestly can't think of anything I liked, other than the plane arriving and leaving on time."
Cons: "The in flight entertainment is a joke, it's a 14 hour flight so why are there only 3 episodes of any tv show? The food was inedible, and beverages were limited to 3 choices coffee, water or juice. I was trying to sleep on the plane but every time a flight attendant would walk past me they would run into me (and I was very much within my seat) and wake me up. They also woke me up to ask if I wanted food twice. The seats were so uncomfortable. I'm an able bodied 20 something and if I am in this much physical pain from flying I can't imagine what an elderly person must feel like after flying Air Canada. The pillow that was provided gave me no comfort what so ever, it wasn't think enough to even offer some back support."
Pros: "Excellent flight"
Cons: "All good"
Pros: "One Time. A very polite staff!"
Cons: "Finding an overhead luggage compartment was difficult. Some peoples luggage is over sized, and some stow two items."
Pros: "The plane wasn't too bad; comfortable and plenty of movies to choose from; the only thing headsets and volum didn't work as well."
Cons: "Airport was a complete mess; I would say I will never fly out of Rome. Air canada wasn't too bad here since we didn't run into any issues with rebooking flights"
Cons: "They lost my bag which was full of important clothing I needed for interviews this week."
Pros: "I liked that access to movies was provided without needing to download an app prior to departure."
Cons: "The drink and snack crew offered extra pretzels to the row in front of me and skipped my row completely. Had to ask them when they were already nearing the end of the plane for this since flagging them down didn't work."
Pros: "It was on-time, left enough time to reach connections and my bag arrived."
Cons: "Flight was slightly delayed boarding in NYC but it wasn't a long delay and we left on time."
Pros: "Not much"
Cons: "Food is awful and the seats are the most uncomfortable I have ever encountered!"
Pros: "Crew was nice and very helpful.. Nice selection of movies.."
Cons: "Food could be improved.. no flavor and it looked over cooked.. Drinking cups could be switched to paper cups.. or recycled one's.. Packaging and overall rubbish could also be reduced. 777 seats were to narrow.. bigger seats are a must for such long flights. Internet access could be free.. with a limit of course.."
Pros: "The in-flight meal was excellent!"
Cons: "I'm tall 6'6" and was stuck in the middle of the center row. I was uncomfortable from the moment I sat down which included extra delay time on the ground."
Pros: "On board facilities and service"
