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!

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.

No frills flight poor leg room and plane was 30 min late

Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!

Getting to Scotland with no luggage (no medicine, no clothes and no club) on golf trip very disappointed

The flight attendants were efficient and helpful. The airplane had malfunctioning equipment. Again, as was the case with my previous British Air flights, the USB port did not work. This may seem like a small detail, but in this day and age, it is important to be able to have charged electronics in order to enjoy such a long flight. Please upgrade your cabins!

The flight was on time and crew were nice, seats were tight and there was entertainment available

Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.

A cookie and a soda, packed like sardines, will never be a positive experience. Also, boarded a 5:30 flight at 7:45pm

Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.

The crew was very helpful and the aircraft was clean. More attentiveness to us in business class.

less delays; there was an hour+ delay on both flights. self serve check in kiosks weren't available for British Airways flights

Terrible! Our flight was cancelled. No other nonstop flights available. Had to rent a car and drive 7 hours!

I really enjoyed the delicious food and the delicious breakfast; I also liked the seat—it was very comfortable—and the service was absolutely wonderful. The trip was smooth.

The food was awful. It had more than 2 hours delay. It was too expensive

They are offering less and less for more and more. They changed our seat that we paid extra to select at the last minute. The seats are way too narrow and my elbows went numb.

My original flight was canceled the day before due to mechanical issues. I had to rebook and spend $129 for a night at the airport Comfort Inn.

From my experience, I see there is room for a greater mixture of cultures, for example, a mix of the nationality of cabin crews, food, music, food, etc.

Fight left on time Food was good Lots of entertainment Very uncomfortable

I was suppose to be preboarded, because of my child's allergies, but it wasn't done.

After we arrived at our gate, security staff changed it to"international", and rudely refused to explain to my wife why she could not go to the nearest restroom.

Didn’t even make this flight bc air Canada caused me to miss it and make an extra stop in Lyon France

I never got to Lufthansa because of Air Canadas negligence.

The flight got delayed 3 hours from Montreal and we missed our connecting flight so it was a long journey

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

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.

Try to humanize onboarding and take AI out. It's embarrassing and useless

no kiosks to check in with- it’s 2024!!! the flight was so hot and uncomfortable - not sure if that’s what caused a lady to faint during the flight but i was absolutely miserable.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

Waited 7 hours at the airport and now I have no way to locate my luggages because they were checked with tags to a flight that was delayed twice and then canceled last minute. I was told my luggages would be routed to my final destination but they’re not here .

Didn't have my boarding pass until Montreal, really stressful and neither Luftansa or Air Canada were rlly helpful.

Please see other message. One flight was cancelled and neither Lufthansa or Air cañada would book me on another flight as they did not have me in their computer(with the numbers you assisted me with) HELP

All good, professional service, and arrived close to on time.

This was a special trip so we booked first class. It was obviously an old plane as the seats weren't that comfortable or spacious. We were delayed 45mins taking off as the "little engine that starts the big engines doesn't work". The powered divider between myself and the next seat in first class didn't work and my electrically powdered seat didn't work so I had to move seats to try and get some sleep. Food and drink were good, crew were great. But I'll never fly with BA again.

Need thicker and wider blankets. Food was below standard especially in the fist leg.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.

Boarding was efficient. Flight left on time. Wasn’t full so we could spread out a bit. Food was ok.

The A350 is a great plane but BA's seating was incredibly tight (eg compared to the same plane as flown by BA's partner Finnair) and with a middle seat it was very claustrophobic

Staff and crew where very nice and friendly. Just need to improve the timming om the meal and beverages.

Lost bag - again. No help from staff at Nice - they have a handling agent who does nothing No emergency kit Try calling BA - they eventually found the bag - now on later flight. Trying to get someone to help in the short term is impossible. If I am unhappy - then I have to log it on a website. The agent said he was only able to help with future bookings - not assist in the chaos BA had caused. IF YOU WANT SERVICE WHEN THINGS GO WRONG - PICK ANYONE BUT BA. Personally - I'm joining ABBA (Anyone But BA) again.

I asked for assistance for my mobility issues. It took over 45 min to find someone to take me to the security. then I was deposited at the lounge and I was supposed to be picked up. No one came. I almost missed the flight. There was no offer of extra water, snacks or anything on the flight. Food was OK given that I am gluten and diary free. Seats were uncomfortable and very little stow away space.

The seat was a bit crowded since the person in front was reclined. It’s my personal belief that if the seats are allowed to recline, there should be more room. The service provided by the crew was the best I have experienced.
