Pros: "Flight crew was fine. Food was good."

Cons: "After more than two hours of delay... Initially the flight takes off was at 8:35... Then 21:20... Then 21:50... Then 22:10. Finally we took off at 22:40... Refund our money klm..."

Pros: "Everything"
Cons: "Nothing"

Pros: "Crew were nice, food on board was ok Given the long wait time at immigration, we did not have to wait for our bags."
Cons: "Rouge seats are notoriously uncomfortable, especially on a 9 hour flight. Rouge Player entertainment sucks, very poor movie selection. Irish immigration took 45 minutes... a ridiculous amount of time in this day and age. My time with the officer took about 30 seconds, so obviously the problem is that they are understaffed...not the best way to start your trip to Ireland after a long flight!"

Pros: "Good service, surprisingly good food, smooth and efficient."
Cons: "The premium seating we paid extra for because we need leg room (my partner and I are 6'+) was the first row behind the 1st class seperation wall...so no way to extend legs by placing feet under the seat in front. Not very comfortable or worth $100 IMO."

Pros: "The 1.5 hours they turned the lights down and stopped the crew from going constantly up and down the aisle."
Cons: "We were traveling from 11 pm local time to 10:30 am local. However they kept all the lights on for nearly the whole flight. In addition, the crew was constantly going up and down the aisle with food or beverages. It made sleep impossible. To make matters worse I’m allergic to dairy and I tried to prebook an appropriate meal but couldn’t and everything had cheese."

Pros: "Customer service crew sorting us out on new flights had patience of saints"
Cons: "Did not make flight, gate crew rude and did not give information."

Pros: "Very little I'm afraid."
Cons: "A lot ohe seats are faulty the entertainment system barely works, mine didn't and even if it did the headphone jack was broken! The cabin is more than grubby, it is dirty with torn fabric and faded writing on dirty plastic. I skipped the meal on the return flights as the outbound were the worst I have ever had! In all honesty I'm not a fussy traveller and never write reviews but Air Canada was so bad I thought it might be useful info for someone."

Pros: "The plain was not full and my section at the back was quite empty so I had seats to my self and was able to lay down. The plane had been recently refurbished and everything was clean and new."
Cons: "Very rushed boarding, this happened last time too. They called for my section to board and I immediately got into line. They made two more call where the staff sounded quite annoyed. "We're still missing passengers" " If you are in section 3 you need to come to the gate right away" he made the second call when there was one person infront of me in the line. Like everyone was in line we just hadn't been processed yet. I don't know why we need to be rushed onto the plane by impatient staff. My entertainment device stopped working in the middle of a movie and didn't work for the rest of the flight."

Pros: "The crew at the airport and on the plane were excellent. We were on a family holiday with young ones and the crew really took care of our needs. They were extremely courteous and attentive."
Cons: "The inflight entertainment options could be more current. We found the options limited... it was a good thing that the flight was short."

Pros: "The flights were great, on time and no problems. I was very comfortable and the food was good. FLight attendents were great except one guy who was not friendly and needed a vacation or another job."

Pros: "Easy flight to Dublin."
Cons: "Boarding could be better organized - staff should make sur only the people in the zones called are in line. Not everyone from all zones. The zones 3-5 line isn't helpful. They should change it to "boarding" and indicate only thsoe called to board should be there. Otherwise, they need separate lines for EACH Zone."

Pros: "Not much of anything"
Cons: "Lack of in-flight entertainment, uncomfortable seating"

Pros: "The staff"
Cons: "No TV monitors and food was bad"

Pros: "On time"
Cons: "Seats very uncomfortable."

Pros: "Great great great staff on the flight. Fast direct service ... Landing in T1 Dublin really speeds things . Checkin in good until.... See below"
Cons: "Plane was late leaving. Food was served around 2-2:30 am. Realize this budget but still 750$... Movies - player kept stalling Check in ... Crazy on bag drop at check in #5 lane in departures in Toronto. Perhaps one more staff at high volume to make sure the folk in the bag drop line actually have bag tags. Travel to same route last year at this time and it was the same experience."

Pros: "Liked everything about this new class of service on Air Canada. Seat was comfortable with good recline that didn't interfere with fellow passengers. Food was excellent, entertainment system was well stocked, flight attendants were friendly and high energy. Even got to use lounge and fast-track security lane at Heathrow."
Cons: "Zero complaints."

Pros: "Decent crew. Decent collection of movies."
Cons: "Overall, this flight service from Montreal for Los Angeles (6 hrs flight) service was worse than the interconnection flight I have experienced in Europe (2 hrs flight). There is no snack provided on this journey and you have to pay for everything (snacks and even the headphones). On the European flights, the snack was provided multiple times for short duration of the flight."

Cons: "Was surprised not to have screens in the seats to watch movies on an international flight."

Cons: "x"

Pros: "It is convenient to take Air Canada from our town and connct in Toronto."
Cons: "The staff are barely polite and do not really care about the passengers. No smiles, Not friendly or welcoming. We trwveled in US last month.. What a difference in attitude. The food was awful, bordering in inedible. (example salad was cold canned corn with shreds of cabbage and no dressing.) Breqkfast was a piece of bread with choice of orange or tomato juice. No tea or coffee. They lost one of our bags, no apology and another company handled the search and return. No reason given to leave it behind. baggage and carry on rules are complex and complicated, and you never know when they will decide to enforce them and penalize you. If you can get there any other way don't go Air Canada."

Cons: "The fact that my ticket said something different from my itinerary and I spent far too long at the counter to get a seat assignment."

Pros: "The crew was so good and friendly. I had an overnight flight and so having a considerate crew is so important. The comfortability was decent for being a plane and long distance."
Cons: "It was a 6.5 hour flight and there was no entertainment. Every additional amenty cost extra."

Pros: "We needed a wheel chair assistance. From Toronto to the gate, it was very good."
Cons: "Much delay before take off without real announcement to that effect. Unbearably heat once we got on board and waiting to take off- afraid of fainting."

Cons: "The flight was delayed by 2 hours. After boarding, it was another hour before the flight took off. I was seated next to a family with 2 cranky children. I chose this flight just because it was supposed to arrive in Miami at a decent time. Ended up sleep deprived at work the next day."

Pros: "Food was ok"
Cons: "Avoidable delays caused a late departure from Toronto, then we sat on tarmac waiting for a gate in Dublin. Eventually had to debark into the tarmac and walk in. Delays caused us to miss our next flight to Munich."

Pros: "I liked the streaming entertainment I enjoyed the friendliness of the crew I was pleased with the Canada air app allowing check-in and tracking of flight"
Cons: "The comfortability of the flight was poor. Both my wife and I were too uncomfortable to be able to sleep on out more than 9 hour flight. Leg room bad, seats uncomfortable."

Pros: "I liked that the flight was not completely full. we had a hard touchdown"
Cons: "1. These days, I have come to expect a complimentary in-flight entertainment system on international flights. This flight had nothing whatsoever. This is ok, but the customer should be warned when making the flight reservation so they can choose whether to bring an ipad along. 2. Food and service were not as good as a recent Air Canada return trip from Roma to Vancouver which had a first rate crew, food, and complimentary beer. 3. The plane was much older than the recent return trip I had and the air was much more dry."

Pros: "The only thing I liked about my flight to Dublin was the fact that we arrived in the correct city."
Cons: "Once again I found the air Canada staff unaccommodating, un-attentive and basically indifferent to the aircraft's guest. In addition I tried 4 electrical outlets on the aircraft before finding one that worked and the reading lights never did work. I would never recommend this airline."

Pros: "Safe and efficient."
Cons: "Poor seat room. Food quality mediocre."

Cons: "Did not appreciate not having a movie screen. Renting an iPad for such an expensive flight is not good business."

Pros: "Once again, attendants were pleasant. Plane was clean"
Cons: "No snacks served, only beverages. We could have at least received one bag of nuts/chips for the flight."

Cons: "The fact there was no entertainment system available for a 6hr international flight is a crime. Apparently there is some sort of app you need to download on a mobile device or computer BEFORE the flight, Would have made a huge difference knowing that."

Cons: "There were no screens to watch anything on for a flight across the Atlantic. And we were told once we boarded that we needed to download the aircanada app in order to get content. Well by that time I didn't have free wifi and couldn't download the app. Very frustrating. I would suggest announcing this before people board the flight."

Pros: "Got to spread out onto two seats since flight was not crowded."
Cons: "Food options. No inflight seat with entertainment screen."

Cons: "I am 5' tall and there was no leg room for me."

Cons: "The person next to us was too heavy to fit in her seat, so she flowed over into my husbands, making the whole trip uncomfortable. In addition she had a smell. Not sure what can be done about it, but it made a long trip really uncomfortable. Service and food was also much better on the South African airlines portion of the trip."

Pros: "Great flight crew, fairly comfortable seats. Made a 10-hour flight pretty bearable."

Pros: "Boarding was smooth and the crew was wonderful!"
Cons: "Air Canada changed my seat assignment at the gate. I had chosen a window-seat, but they switched me to a center seat. Also, there is no free in-flight entertainment if you don't have your own tablet/smartphone (neither of which I have). You can rent i-pads. I wish I had known that before flying."

Pros: "Great crew. Gracious and helpful."
Cons: "Kayak was a nightmare to work with."

Cons: "The fight itself was fine. Not great. Not terrible. But the airline lost my son's suitcase and has been entirely unhelpful ever since then. Now we have been stuck in a foreign country without clothes and toiletries for 36 hours and Air Canada's "helpline" has been anything but helpful. They can not find any information on the location of the suitcase and hope that they will find it in another 48 hours. Rediculous!! I will never fly them again and suggest that you save your money, effort and vacation by flying with another airline."

Pros: "The flight crew were nice and friendly, though they weren't very on top of trash pickup, but they were chipper and that's always better than grumpy crew that are super-efficient. Also, our luggage made it with us despite a tight connection."
Cons: "53 minute hold time to call center (before my call was even answered) to order vegetarian meals for flight (the day before flight) -wish that could be done online, vegetarian meal request not transferred to new flight after we missed our initial flight due to first flight delay, lights not working properly for half of flight (sleeping child under spotlight), the pasta dish, collecting garbage in my seat throughout flight (particularly after meal service), cramped seating, lack of entertainment, and they are now charging for alcoholic beverages on international flights. I'm not a big drinker, but I still enjoyed that perk."

Cons: "Had to use your own electronic device. Did not know that you had too download an app prior to boarding. No personal control over cooling/heating. Never fly Air Canada Rouge in the future"

Pros: "Toronto is a lovely airport, and it's a short hop to Europe from there, which is why Air Canada Rouge is ok for the trip. It's important to remember that their no frills approach means no TVs. Sleep or plan accordingly."

Pros: "Again the crew was enjoyable and the timliness of the flight and the boarding process was great. Also I appreciated the blanket and pillow given for the flight"
Cons: "There was no entertainment for this 6.5 hour flight, I was very disappointed with that."

Pros: "Flight crew was nice"
Cons: "Where do I start. Plane was very late taking off but the biggest thing was that I paid extra for a premium seat and I think it was worse then any regular seat. Waste of money!! Now the food. It sucked and there wasn't much of it. Dinner was at best skimpy and " breakfast" was a piece of some kind of cake. That was it!"

Pros: "Food tasted good"
Cons: "How close together the seats were."
