Airline reviews

Pros: "Seat was comfortable as I had the exit row"
Cons: "Flight was late by an hour taking off from DXB."

Cons: "Travel agency did not notify me that I needed to get a Yellow Fever immunization"

Pros: "Polite, helpful crew"
Cons: "Nothing, would recommend"

Pros: "Crew as always with air Canada were very accommodating. Always smiling!"

Pros: "It arrived on time."
Cons: "The temperature in the cabin was way too cold. People we wearing their jackets and when I mentioned it to the cabin crew member she said a few other people would have to make a similar comment before she could request turning the temperature up. There was also a glitch in the system so that the reading lights for each seat could only be operated by the seat directly in front. The food was very uninspiring and poorly presented. The tea and coffee were awful!!!!!! The choice of movies,etc was very limited. Thank goodness it was a night flight and not too long!"

Pros: "New plane in the excellent condition. Leg room in economy not bad. Crew friendly and efficient. Boarding worked well."
Cons: "The main meal was pretty dreadful. Grilled chicken with what I think was mashed potato, but it was difficult to be sure. Watery and tasteless. Accompanied bizarrely by a tomato sauce (which did taste of something). Hard to identify the ethnicity."

Pros: "Really nice comfortable seats, amazing windows larger then usually with new technology. Food was ok. It was nice that crew constantly was offering drinks"

Pros: "nothing"
Cons: "See above - seats worn out, entertainment worn out, Crew battling old tired aircraft. Massively overpriced. Bring on WestJet direct to Ottawa."

Pros: "Exept food everything was awesome"
Cons: "Food"

Pros: "only The crew inside the airplane and the airoplane"
Cons: "Every one in Lufthansa are so rude expect the crew"

Pros: "Service was impeccable. In flight entertainment was good"
Cons: "Food was nothing special"

Pros: "The crew were very good. In any case, I shall fly with AC again."
Cons: "Lining up to check in with bags. The customers were "sorted" but I finished up on a very long line with only one person serving; after 30 minutes, that person just wandered off, presumably for a break. We, on the queue waited for 15 minutes for a new person to return. When it was my turn to check in the process took no more tan 30 seconds whilst for others it had taken 10 minutes and more. Dreadful experience. The choice of entertaining films was limited on my flight; normally AC has a wide choice."

Pros: "Beautiful new 787"
Cons: "Entertainment options could be more plentiful."

Pros: "I am 6ft 1 / 185cm and the leg room was OK for an economy flight. Food was OK for airplane food. Staff were very friendly. Overall very happy."

Pros: "Great food and good space for economy"

Cons: "Ran out of food.."

Pros: "Clean, friendly crew remembered how we had our tea/coffee from the earlier service"
Cons: "Economy is never very comfortable but was better than a lot of other airlines"

Pros: "Entertainment"
Cons: "My seat was wet and i had to wait quite a while for it to be rectified. I asked to sit on a crew seat at the back of the plane and was told that i would break it. I found this rather disgusting . Seating plan is very crammed like sardines"

Pros: "Crew were good"
Cons: "Seats were too tight. Entertainment was mediocre"

Cons: "I wasn’t able to check in online and therefore wasn’t able to update with my dietary requirements which meant I couldn’t really eat anything that was given. I was told at the airport that it needs to be submitted 24 hrs before the flight and there was nothing they could do. Really unfair and not on."

Cons: "Lost luggage!"

Pros: "The hot dinner was good"
Cons: "The pudding was poor, it was just a wrapped cookie. The movie selection was terrible! Most of the films were very old!"

Pros: "great service from start to finish would use again"

Pros: "its was smooth"

Pros: "everything"
Cons: "no entertainment"

Pros: "I was reading so much about how cramped and uncomfortable the seats on Air Canadas 787's, but I don't think their product is any worse than most other economy class products out there."
Cons: "Their "continental breakfast" was a dry piece of banana bread and yoghurt. No jam, butter cheese or other spreads to compliment with your bread. Most disappointing "continental breakfast" I have had on a plane!"

Pros: "Ease of boarding - no long queues. Offer to put hand luggage in the hold with no charge."

Pros: "Staff all friendly and helpful, both at desk and in plane. Seats were pretty comfortable with sufficient leg room (I am tall), but if you are a wide person (or next to one) it would have been pretty cramped. Neither of my flights (to Newfoundland) were full so we all had a bit of extra space. Food was adequate but could be improved with fruit instead of dessert."

Pros: "I sat next to quiet and pleasant travelers. Flight left and arrived smoothly"
Cons: "Boarding was one long queue.... My row was skipped in the meal service when they had to restock and restarted in the wrong row. Attendants never responded to call light. I had to verbally call out as attendants passed by. On the third attempt one actually stopped and brought the meals. No apology given."

Pros: "Friendly crew, modern aircraft"

Pros: "Pretty standard flight...nice crew, free drink, left and arrived on time for the most part. Liked that I could check in early to arrange a seat."
Cons: "The seats could have been more comfortable. Had a couple knees in my back."

Cons: "service desk unable to reroute me on a different flight even though there are seats"

Pros: "Boarding was very well-organised ands clearly explained."
Cons: "USB socket broken and non-functioning. Plastic fork snapped and shed tines. A truly ghastly movie selection."

Pros: "Helpful and considerate staff when my friend was sick"
Cons: "The delays to leaving the airplane port."

Cons: "Toronto international airport was very crowded. too many people , not enough facilities. You have to line up to do anything, even buy a bottle water."

Pros: "Flew to and from LHR with Air Canada after flying Air Transat for years. Both flights were professionally managed with the crew in constant availability. Not over the top cheerful, but ready to attend to requests calmly and with attention.beverages etc. were readily available."
Cons: "Low-quality food and small portions for a 9 hr flight."

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."

Cons: "I had to eat a big pizza from outside.. nonsense food and only water being served 24/7 as if I am from a desert..bullshit."

Pros: "Nice and safe flight with little turbulence"
Cons: "Not enough room! And stuck between two fidgety guys. One drank six little bottles of whiskey."

Cons: "They could have done the boarding different. There was a bit confusion about when to board."

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."

Pros: "Overall a good experience. Had to pay for food but it was quite good so I didn't mind. Supposedly the crew were short staffed but I found them attentive and helpful and to be honest I believe the people who complained may have been a little precious."

Pros: "Friendly efficient staff"
Cons: "The plane was a bit dated so the seats were smaller the Luthansa"

Pros: "Very professional but also pleasant. Clean, good food."

Pros: "I really liked how the crew on our leg to Heathrow made sure we were comfortable and asked often if we wanted more drinks (water, etc). We had a delay in landing due to weather but we were able to make our connection because they called ahead to customs and we were able to go to the front of the line. That's service!"
Cons: "Bathrooms got kinda dirty about halfway through the long flight from Toronto to Heathrow."

Cons: "flight was cancelled and I was offered a flight through Montreal with Long connections so I cancelled and flew the next day again through Montreal but with better connections"

Cons: "Seats are always too close to the ones in front , crushing knees."

Cons: "Entertainment system is outdated and not functional"

Pros: "Large comfortable seats."
Cons: "You now have to pay for drinks on British Airways flights"
