I liked the reliability. I liked less the chair comfort...

I didn't have any problems during my flight. My main issue is with airlines in general, they keep offering less and less every year, AirTransat is no different.

We are a senior couple (70+) and chose emergency exit seats so we would have 2 seats together and neither of us had to sit in a middle seat. My husband is type 1 diabetic on an insulin pump and I monitor his blood sugar levels. I am 5'9" and 250 lbs and found the seats extremely uncomfortable. Toward the end of the flight I developed diarrhea which lasted a full 24 hours.

I was supose to have a carrey on incluided for each passenger and they made me paid 75$ each at the gate.

I did not like I have been charged for my carry on

It was very good but no tv but the experience was great

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

Nice complete meal included and great services. Plus the plane was very clean.

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!

Compagnie efficace et bons prix. Les sièges en classe club pourraient être plus confortables.

The flight was good overall. Everything went smoothly, although the landing was a bit rough. Still, it was a pleasant experience

Simply as follows:- First, there was no vegetarian option for the meal Second, only 2 washrooms for the entire economy class.

I loved my experience. Very safe, Very informative and very friendly.

Check in person said there would be lunch. We were first class passengers and lunch was chips.

On the trip to Rosario, we raw dogged it for 7 hours. No wifi, no charging outlets, Gilbert girls on every third row monitor with no audio. It was better on the return flight—at least we had screens and earplugs.

Good trip, excellent attention. I like Copa Airlines, the best. 👍🏻

I was supposed to have a lay flat seat but they switched planes and there was only a chair

landed in panama it was in terminal one. We had to take a bus to terminal two for customs. Then back to terminal one. It was very frustrating. Then, on the way back from panama it was the same situation. We had to go back and forth between terminals to check in and drop our bags and then to board. When we were leaving, we had to wait in line for the boarding area and go through another gate security process. They told the bottles of water and coffee were bought while in line in the airport after we passed the main security. Ridiculous (and expensive). A much better communication system is needed.

I liked the friendliness of the crew and comfortable flight. All good.

LOCKED MY BAG WITHOUT CONSENT. Had to have my zippers cut upon arrival in Costa Rica.

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

Very nice and clean plane. Transit time between flights was tight though

So far so good but food and entertainment are not available for this flight

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

The plane used to go to Chicago was a bit outdated and needed a refresh

The check-in and passport submission was complicated and repetitive, due to the poor communication between Air Canada and United. There should have been a single set of instructions and a single questionnaire that provided the data for both airlines.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Internet was not working for a bet . Hard to order food with our credit card because it was not in your system .

Booked economy through United - air canada treated it as standby and was almost refused boarding.

Flight was delayed twice which made our arrival extremely late (actually into next day). Not an easy travel. But when we requested assistance for boarding we were really impressed with how they helped us! Strongly praise their assistance.

every single person involved showed their joy, working in the airline industry - it created a very pleasant atmosphere for everyone

For boarding, after family with youngsters, you should have 65 and over. Whatever rules, enforce them. It’s frustrating for those who respect them to see aggressive people rush to the gate out of turn…

A snack would have been nice instead of having to buy food.

The plane was new. Should give more options on food.

No food other than a tiny snack. The flight is too long for not having a more substantial food option, other than buying the overprices and mostly non-plant-based options from the menu.

It was a refreshing experience from the past few times I have travelled with Air Canada.

rerouted on red eye. arrived 9 hours late with no luggage. still missing after 3 days. up to 45 day to deal with it. SHAME

The crew is super friendly and helpful , boarding was quick and easy , the prices are too high for a an airline that doesn’t provide complementary meals or snacks for long flights

The flight crew was nice and courteous. The food was terrible. There are no in-flight entertainment services, the plane is outdated and dilapidated, and the flight is delayed. Both from Newark and Montreal. Too bad.

Seats are absolutely not comfortable and large enough. There’s a limit and you stepped over it. I understand that there’s a business class, however for the price it costs, it’s just plain stupid for a 50 minute flight.

The crew was great! They waited for me as Air Canada flight was delayed by 1:15 hours from Ottawa to Toronto. I am a bit disappointed that we could only use wifi for entertainment but I survived! The only thing I would of liked is a more comfortable seat. The seat cushions are not thick enough for flights longer than 3 hours. Aside from that, everything was great.

They should provide water to passengers who ask for it

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral

No food, terms when selling are not clear. To pricy for the service in general

Flight to Bogotá delayed by 3 h Missed connection from Bogotá to Guayaquil. Avianca unable to bring us to Baltra on time Overall delay 36h. We missed boat departure from galagos. Overall 10 day trip needed to be cancelled. Avianca was completely un-professional.

The seats were very uncomfortable. I would have upgrade or got different flight if I knew. I usually sleep in the plane but I couldn’t sleep at all. Very uncomfortable. Also no food or drink everything was to purchase, and that’s u usual for international flight.

The temperature was cold and the food that we had to pay for was awful. The crew didn’t even offer a free glass of water. It was a long, expensive and uncomfortable flight.

My international flight from LAX to Argentina had one free check in bag included in the price I paid, however your crew in LAX made me pay $95 USD to carry it on! Please note I had only on small size luggage (carry on size) and one backpack. I demand my $95 USD back that you guys charged me illegally in LAX.

Voo longo nem mesmo água ou gelo é servido, se quiser tem que pagar. Embarque é péssimo, mau atendimento.
