All good the seats a little tight and no I pad screen

Everything was good except the fact you charge more for a carry on bag vs a check in bag and to top it off in US$ that was not impressive

Our flight was cancelled at the last minute for maintenance reasons and we were rebooked on a late flight when we purposefully booked our flight to be home early due to work.

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

Flight was delayed over 2 hours, then landed at a different airport!

The whole experience from check in to deboarding was fantastic.

Just an evening before they canceled my ticket and offered me ticket costing 3 x times more than. I will not fall prey to these scams,Will never book through kayak now. Such a bad experience.

was okay except.. 1)the porter check in webpage doesn't let you print your boarding pass from home 2)that there was a 90 min cut off for checking in on the kiosk in general, and to print a boarding pass, even tho i checked in online already....

Great! Personable crew. I love that they pour complimentary beer and wine.

I love the 2 seats per row. More room. The crew were excellent.

Check in slow even though completed online check in, there was no bag drop available so had to query for 90mins as only 2 staff on desks.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

Not so much porter it's your site! Not good

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Never book through a third party. Book through Air transats website. Terrible process to get help and many issues happen with them and sister companies because half the flights you book with them aren’t even through air transat.

The plane was pretty full, and we dis not have any includes meal for our 4h30 flight? And on-board entertainment wasn't available, there was no TV or plugging to charger your device on the plane. They told us to download an app if we wanted to watch movies but it never connected, that was a disappointment, the r we st was very good though and the crew were really nice!

Seats were very tight especially for first leg of trip.

Not necessarily a Transat issue but it took 2 hours to go through immigration. Tried to reach out to Transat for resolution but was unable to reach an agent.

The flight was excellent, once it started, however we were delayed two hours when the first plane’s engines wouldn’t start. They found another identical plane and transferred us and our luggage in under two hours and made up almost an hour in the air.

Really low cost trip for the huge amount I paid…o paid 550 dollars just for the trip, one way trip, plus 95 for 1 luggage’s and the second 135 dollars…no blanket, not headphones for entertainment, food was served after 3 hours and 2 hours after, breakfast was served Bad, low cost company for high prices

The food was great and the service and attitude was amazing!!

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

It was an OK flight with below mediocre service by their flight attendants

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

Flying in the Dreamliner is always comfortable. Though the food options for Air Canada aren't great.

Flight got delayed for no reason. And Air Canada was doing 3 boardings via the same gate. It was chaotic!

I n the Toronto airport I had trouble finding my zone. It was 47. I went from Zone 1 to the end of the line.didn't find it. Then saw my zone somewhat by accident over by where you first come in. Signs could be more helpful or more personnel directing people like me.

Wonderful airline. All staff were pleasant and helpful. What is sad is that it wasn’t grand gestures just everyday pleasantness and friendliness that are missing from the other airlines I have flown recently.

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

Orderly boarding. The flight to Montreal was difficult to get to on time, but had help from staffer.

Orlando to Canada, despite being close and an international flight, the plane was not at all comfortable. It felt like the chair was being pushed forward, in addition to not having a TV and having to choose from a tiny glass of drink, for example, water or soda. I couldn't have both. When I asked the flight attendant for an extra glass of water, she looked at me with an ugly face. This is ridiculous. They don't want to give water to passengers. I will never fly with this airline again in my life.

In flight entertainment system did not work across the whole plane for entire flight. Seats were very cramped. Cabin temperature was freezing cold. Crew was miserable and answered everyone in a short and barking manner. I’ve flown air Canada many many times and never had an issue. But this was unpleasant.

They screwed up so bad, I asked for a short check for my luggage since we had a 21 hour overnight layover in London at a hotel. They said I have to receive my luggage in London because it’s an overnight layover. Get to London, nope, my bags aren’t coming off they are staying in terminal 5 over night and going straight to Ibiza. So we had no luggage for a whole day and basically stuck with no clothes or washroom stuff. Finally get to Ibiza and my luggage is completely smashed and damaged and missing a wheel. Now I have to drag this 50 lbs luggage around Ibiza islands for 10 days. Wtf. So pissed off Air Canada is LITERALLY THE WORST AIRLINE IN THE WORLD

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel

Not bad. We had preboarding tickets but the preboarding was badly managed. We lined up behind all the parents with little kids etc and when we got to the front of the line the attendant deliberately turned away from us and ignored us until I asked to be allowed to go to the gate. She started telling us that we had to wait until I told her we had preboarding then she let us through.

Everything well done and customer oriented There entertainment system is difficult to navigate

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

The flight was delayed and I was stressing the whole time about whether I would make my next flight.

This was the best carrier, comfort, service, good food, on time experience on a long haul flight. New, clean, quiet, smooth aircraft!!!

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.

my flight was cancelled. next one scheduled 2 days later. no hotel provided. worst airline experience ever
