Pros: "The food was good"
Cons: "My girlfriend’s Tv stopped to work in the beginning of the flight."
Cons: "Online check in was not accessible."
Cons: "Being near the back of the plane we missed out on all the food options except for the chicken wrap which was horrible. You ran out of everything else."
Pros: "We didn’t crash."
Cons: "Continue not to crash. Thank you."
Pros: "The flight itself was fine but AC could splurge for a gate rather than bussing our to the tarmac"
Cons: "The enertainment system was down for over half the passengers and only returned to spotty functionality two thirds of the way through the flight. I gather after some other passengers disconnected. Clearly the system didn’t have enough bandwidth to support all 350 passengers. and why no wifi?"
Pros: "Crew was friendly and polite"
Pros: "only The crew inside the airplane and the airoplane"
Cons: "Every one in Lufthansa are so rude expect the crew"
Cons: "Put on Turkish air landed 12 hrs late lggage still missing"
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."
Cons: "Flight was delayed My wife and I got separate seats Screen and audio on the entertainment system didn't work"
Pros: "On time Nice crew Smooth flight"
Pros: "Being the first passengers to exit the cabin after a 5 and a half hour flight is definitely a perk, as well as getting one's luggage (a priority tag is attached to them) immediately upon getting to the carousel, an other. Leg room and more space is also great."
Cons: "The only board menu was not exhaustive, considering one pays over $500 USD to move up to business class."
Pros: "The flight attendants were very nice and helpful. When they passed out dinner my husband and I were asleep, we woke up when they were serving drinks (right after). They got us our food. On our flight over however we didn't get options on food since they had run out. The flight crew was nice though."
Cons: "Unbeknownst to either of us the Air Canada Rouge is a low cost carrier international flight. It didn't have a player in the seat, or even old school TV's. You had to use your own device on their WiFi which was SLOW and the sound went out. The seats are small with very little leg room. I'm 5'1 (156cm) and my legs almost touched the seat in front of me. Also the airport was the biggest hinderance of getting to the gate and the airplane. After customs, to get to our gate we were told to wait in another line while they went through nearly every passenger again... And checked bags. Since it was taking so long they would let some go through without checking them. It was strange to say the least. We eventually left the gate late but made up for it in the air."
Pros: "The flight attendants were very friendly and tried to make up for a very delayed flight with kindness and attention. They were the saving graces for that flight not being a total disaster."
Cons: "The incoming flight was delayed which pushed our flight back. After we were done boarding, we sat on the tarmac for almost another full hour and weren't really told why the incoming flight was delayed in the first place. My IFE wasn't working so I couldn't even watch a movie or do anything while we were waiting."
Pros: "Nothing"
Cons: "For business class the accommodation was appalling. The seat would not even recline more than a couple of inches, let alone lay flat which is what one is paying for. The touch screen entertainment did not work. The flight arrived too late to make connections - again. The boarding agent at the gate in Los Angeles was one of the rudest and most arrogant men I have ever encountered. I complained to the plane's Captain about him, as he was going through. All the business class passengers around me were commenting on it. One was even filming his egregious behaviour for Facebook. He alone was enough to put one off Air Canada ."
Pros: "Fast boarding, no delays."
Cons: "I always fly Air Canada but I guess I wasn't aware that Air Canada Rouge was a completely different species. No entertainment at all. When we got on the plane, the sun was shining through the window & floating in the air was a mind-boggling amount of dust, feathers, etc.. flying all around... like the air was completely FILLED with them.. you couldn't get a breath of oxygen. This irritated my respiratory system immensely. They also had children helping out the flight attendants which was cute, until the one girl who had just served water to the entire plane broke out into an awful fever. They were putting ice packs on her head, giving her meds, & eventually she had to get carried through the airport. This was 5 minutes after serving water to an entire plane of passengers. I ended up getting extremely sick & missed almost a week of work. Not sure if this was the cause, but it makes sense. I will make sure 100% to never fly air canada rouge again. For $400 a ticket... doesn't make sense to experience this."
Pros: "Overall good flight in terms of smoothness, safety, timeliness, etc."
Cons: "No enrertsinment without downloading google app for phone or pad. Short announcement about this made shortly before flight and we did not react in time to do it. Thought I would read but overhead lights broken; complained three times before fixed."
Pros: "Decent movies."
Cons: "I separated from my 2 daughters and husband because they did not allow me to pick seats or check in online. I was stuck in the seat immediately in front of the stinky bathroom in a seat that didn't recline, had no hdmi charging port and was pretty much continuously crowded by bathroom-goers. In fact, so many bathroom goers grabbed the seat in front of me that they touched my movie screen about 7-8 times, causing the menu to pop up and interrupt the movie. Otherwise, the food was gross and one of the flight attendants was very grumpy."
Pros: "Service food on time flights"
Cons: "No movie for such a long flight."
Cons: "My flight from NYC to Montreal was delayed 4 hours due to a storm that had passed earlier in the day. That was understandable, however we then sat on the tarmac at the gate for an additional hour because Air Canada's entire computer system suddenly crashed. We finally got to the runway and in the middle of takeoff the pilot slammed on the brakes and aborted the takeoff because he did not reach high enough speed. It was very scary. I was supposed to land in Montreal at 10:20 pm but arrived there at 2:30 am the next morning."
Pros: "I liked the friendly crew members"
Cons: "1. Could not reserve seat on the return flight and still got charged for it. 2. My seat did not have the new outlet for phone jack and USB charger. I had to use old headset outlet on the arm-rest which did not work. 3. Planes delayed on both directions."
Cons: "See above."
Cons: "I couldn't board the plane due to new documentation requirements for travelers transiting in Canada. I understand the rules of the internet fare (no returns, exchanges or cancellations) but the customer service was awful. They didn't offer me any other alternative but to loose full value of the ticket ($1700). Nobody (kayak, vayama, air canada or brussel airlines) gave me any kind of information about those new requirements and I ended up cancelling the whole trip as I couldn't find any other flight to get to Europe. Really upsetting...."
Pros: "Arrived early at check in counter and was offered to catch an earlier flight"
Cons: "Was not able to use a toddler booster for my daughter"
Pros: "In the airport Chicago to Montreal I met a nice person he made my boarding pass to me. I love the service !!!!!! Said Thank you so much for your time to getting. Dory Clothilde"
Pros: "The crew members were polite and I know they were trying their best. I can't fault anyone individually for their performance."
Cons: "Although no-one specifically ruined the travelling aspect of my trip, being delayed, cancelled out due to weather, missing a whole day of my trip (out of a short 3 day vacation), never getting my baggage, and then damaging my baggage when I did everyday retrieve it, is unacceptable for an airline to get away with. They will certainly be getting a letter of complaint and a request for a refund."
Cons: "Air Canada was one hour late leaving the gate. This in fact was a great improvement as when we left Montreal on Dec.21 they were 4 hours late and in the best of xmas cheer didn't even offer us a free drink. Way to go AC."
Pros: "The fact that there were several vacant seats helped with finding room to stretch out."
Cons: "Nothing in particular."
Cons: "My traveling partner - Giovanni Medina - was given ill properly prepared food. He ended up getting food poisoning. We had a connecting flight in Montreal to Orlando (our final destination and home), he was suffering during the 2 hour lay over with an ill stomach and then had to suffer 3 more hours on a flight home. He was stopped from being able to go to the bathroom before takeoff because they needed him seated, but he immediately started vomiting right before we took off. He then spent the rest of the ride sick, they allowed him to move to the back in order to use the bathroom rather than the vomit bags, but he was not comfortable at all. He spent the rest of the night after landing in the bathroom continuing to vomit. We chose this airline because of the rave reviews of the food, entertainment, and hospitality of the crew. The latter two were certainly true. We definitely wanted to make sure that you knew of situation because this was a seriously uncomfortable situation for him and we would not want this to happen to anyone else. He had the chicken meal and the meat pastry on the flight."
Cons: "Air Canada over booked the flight from toronto to Montreal and approximately 10 pax were surprised - at the gate!!! - that no seat is available on the plane although we booked this flight months in advance. It is a shame. Although we recieved 200 dollar compensation check it does not cover damage has been done for me at this trip because of my late arrival to a very important business meeting. It is really not fare and shame."
Pros: "Going through customs and immigration in Canada before returning to the US is very convenient and saves time after you land."
Pros: "In general, everything is fine. Boarding was good"
Cons: "Lack of food options for people with celiac disease. No ingredients on the dip in carrots and celery dip. Was told it was gluten free, but had a very bad reaction to it."
Pros: "Friendly crew. Boarding was very chaotic and our seats were originally booked together and someone needed up separate. In the end, the crew worked it out for us and we were satisfied."
Cons: "I've flown this airline a few times and the seats are pretty uncomfortable."
Pros: "Crew service in the plane was very nice, plane was cold and clean as it should,"
Cons: "Lost a flight because they closed the door 20 min before departure, no calls where made to passengers ... I was delayed by airport security and by the time I made it to the gate it was already dispatched, flight closed doors 10 min after it was scheduled to board, very efficient boarding crew that left 6 passengers on the ground !! Since it was a short flight between Toronto and Montreal they gabe me a seat in the next flight which had a delay in boarding (30 min) and then delayed departure too another 30 min ... All in all i spent almost 5 hours in the airport for a 1h flight"
Pros: "The crew was polite and friendly."
Cons: "The seats were very small. I was flying Premium Economy, so it was tolerable, but my daughters were flying economy with very hard seats, very little room, no snacks and no entertainment. It was the Gulag! I can't imagine it being worse for them. On a short domestic flight, it may be tolerable, but for a long international flight across the pond, it was a nightmare! Also, please stop serving those hot pockets as a snack and please stop charging for potato chips and snacks unless you plan to serve a substantial meal! A 400 calorie meal is not going to keep anyone satisfied for 10 hours!"
Cons: "Flight out of Newark delayed so we were going to miss the connection. We were rebooked to fly via London but we lost 6 hours in Rome. Air Canada attendant at Newark said the flight was always delayed and passengers regularly needed to be rebooked. You should recommend air Canada cancels selling this itinerary or bringing the Newark flight forward to de risk any delays"
Pros: "Entertainment system was awesome. Flight was comfortable. Crew very friendly."
Cons: "Checkin staff at airport was not friendly. Airline cannot allocate seats together even though booking was done months in advance. seriously!!!"
Pros: "I think a little more leg room compare to some economy flights."
Cons: "I was very unhappy that I could not sit with my husband both ways when we booked the flight together. And we got middle seats which we hate and requested aisle seats. We were also initially placed extremely far away and I was able to change seats to at least being closer, but not together. There was a couple that was throwing a fit that they weren't sitting together in my husband's aisle. The water they provided came from a pitcher and not a bottle and it tasted nasty. I did ask for hot tea on one of the flights and was told they had nothing hot. My tray table was dirty. Sticky stuff on the buckle of the seatbelt. Used plastic cup by my seat when boarding."
Cons: "When boarding the plane, they called the zones too quickly. Then there was an Air Canada representative giving bad directions to the passengers as to where to get in line. Then she got annoyed and was disrespectful to the passengers as they were trying to get in line. She needed to give better directions or change the way they called the zones. Air Canada knew the flight to Montreal was delayed when we left London. They changed our reservation to Toronto to a flight that we still couldn't connect with because of timing. It would have been easier if they were more realistic with the timing of the flight and booked us on a later flight to Toronto."
Pros: "Must bring your own electronic device"
Cons: "The temperature in the cabin was Frigid, even with blanket, 2 pairs of socks my coat & scarf I was freezing!"
Pros: "The airline personnel in Montreal was accommodating when several of us missed our connecting flights, automatically providing a hotel room and food vouchers for each of us."
Cons: "We were delayed an hour because of a miscommunication with the refueling truck in Montreal before the flight came to Bradley. Then, we sat almost another hour on the tarmac at Bradley Airport because the flight plan was not approved. This caused me and several travelers (out of a small flight of approx. 20 people) to miss our connections in Montreal. Miscommunication seems to be normal for AirCanada, at least in Montreal (almost missed my connection on the way home, too). I will not fly again with this airline in the foreseeable future."
Pros: "We missed our connecting flight due to a delay and we were automatically rebooked on the next fight. On an US airline, we would have o stand in line to get that done. We traveled on Rouge, from Venice to Montreal, and it was better than the reviews I had prior. There was an outlet to charge electronic devices and the app was easy to use."
Cons: "The delay was due to getting baggage loaded. 1.5 hours. There is an issue there."
Pros: "Nothing"
Cons: "Worst flight ever. Had a technical difficulties 3 times in a row. Had to be cancelled and put on the next day and again same thing over and over. So missed all my connections. Cut short my vacation. Will never flight air Canada again."
Pros: "Flight crew was friendly."
Cons: "Horrible smelly crampy cloth seats, awful food, they don't offer complementary wine and beer for international flights like other carriers, no tvs in the headrest. The flight crew works slower then I have ever observed in my over 200 flights. Took them 1hr 40min to serve what they called "dinner", Delta and others knocks it out in 30!!! And don't get thirsty, You'll die of dehydration before you get a drop of water. They treat ice like its gold. 2 cubes for each drink. If u ask for more u get one more cube. Lol. It was just a horrible experience! I will never fly Air Canada again."
Pros: "Nothing. Worst airline ever. Air Canada's customer service is AWFUL."
Cons: "My sister is still stuck in Paria trying to get to Casablanca because Qir Canada changed her ticket to Royal Air Maroc in the system but failed to pay the ticket!! She's been traveling from Seattle to Casablanca for three days and she's still not here yet! And I'm going into labor very soon!!"
Pros: "Very nice people, seats large enough"
Cons: "impossible to work on my computer, plug without enough power turn off automatically"
Cons: "They charged us 25 dollars for a carry on bag which was unfair. They didn't charge anyone else. When I came back I was not charged. I would like a refund. The people were very rude! I take that bag on trips weekly. I should have not been charged."
Pros: "The flight was comfortable. Entertainment choices were varied and generous."
Cons: "o'Hare needs an upgrade."
Pros: "Entertainment selection was excellent and the liquor selection exceeded expectation. Very smooth flight."
Cons: "Didn't give us US customs forms, had to ask, only got one, had to ask again, and then rushed to fill them out and THEN customs threw them out and we had to do everything on the computer. I would think that the crew would be familiar with this process at their home airport and not waste our time. Also, no one could tell us if we would have to go through security again and if we could buy any liquids in Paris duty free to bring home due to the liquid rule and going through security. Just a wildly uninformed airline (asked our crew and other AC officials) they couldn't answer a few simple questions."
Pros: "I got to where I was going."
Cons: "Air Canada acts like a European low fare airline when it is actually just a major domestic carrier that nickels and dimes for everything and charges full cost."
