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.

I think I'd sum up my experiences on this flight (Edinburgh to Toronto) by saying that Boeing 737s are simply too small for long-haul, transatlantic flights. The crew were excellent, the food was pretty good and the in-flight Wifi was a bonus. But 7+ hours on a narrow bodied aircraft with a single aisle and no in-built entertainment system, is a tough stretch - queues for the few toilets on board were lengthy at times; plus whilst the crew were doing food/drink service the aisle is blocked. It encourages you to stay in your seat the entire time (not great for those who need to get up and move around regularly) and the legroom is tight anyway. If this was priced as uber-budget, you could perhaps argue that you're getting what you paid for......but it wasn't and the price we paid was pretty standard for such trips (around £500 pp). I'd therefore urge caution and check the aircraft that is being used if booking with Westjet for flights to Canada from smaller regional airports on the Western edge of Europe. They do operate Boeing 787s from London and other major European centres - but it seems that if travelling from Scotland/Ireland the 737 is the aircraft of choice.......

Switching flights in Halifax was a nightmare. There was no agent waiting us when we disembarked to provide my mom with gate to gate assistance as we arranged. Our flight was delayed so our window to catch the other flight was very tight. The airport was poorly marked as to where to go. The plane was fairly crowded and space available was cramped.

Flight was delayed for 5hours. Food vouchers just aren’t good enough

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

It was disappointing to see the huge number of people who were allowed to board who were claiming to either be disabled or needed extra time to board who practically ran to the gate as soon as boarding opened. One of the female flight attendants in the premium economy section refused to let a lady with an infant use the toilet next to row 9 to change her baby even though the path back to the rear toilets was blocked by staff and trolleys and said she would have to carry the baby to the toilet during the descent phase when turbulence was present. The passenger refused and the baby had to wait until landing. It would have been no problem to allow this infringement of weathers petty rules. The flight was also very cold due to a cold draft throughout the flight from the bulkhead ceiling which was not controllable.

While I appreciated the food (it was unexpected), it was interruptive for sleeping. We paid extra for reserved seats, but when we checked in they gave us different seats. I had to call WestJet arounf 11:30pm the night before our flight to get this fixed. We were give seats in the emengency row to resolve the issue.

Please make more option. And be more precise on the type of food you giving. Diner and breakfast can be different

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

In spite of purchasing premium, I felt it was perhaps the most uncomfortable seat I have flown in. The base was either broken or poorly made and had no support. Even placing pillows and blankets on the seat (1D aisle) didn’t help. It made for a long and mostly sleepless six hour flight. Crew also were very loudly talking to each other through the night making it very hard to sleep. It was purchased for the price, so I get the risk, but was not impressed.

All was good except that the option to purchase wifi for texting throughout the flight didn't work. My partner and I both tried via the app, Chrome and Safari, we tried all payment options. Nothing worked. He was able to get ok blonde with he full coverage option, but it's nice to what we wanted or needed.

The flight departed more than an hour later than expected. The flight itself was good. No other problems.

It was pretty good. The transatlantic flights can be tough on any airline, but this was a decent experience. The only thing I disliked was the airline crew moved my carry on bag without telling me or explaining anything. If I was sleeping during that part, I would’ve assumed it was stolen.

it was by far the worst business class experience i've had. the food was awful, the staff was worthless and lazy, the drinks were warm, no blankets. dirty bathroom.

I could not even make this flight due to Air Canada delay on my first flight. I had to be booked with American Airlines and arrived 13 1/2 hours late. Terrible customer service.

Bad, we had 3h delay without clear understanding, which lead to missing my connection flight.

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

I didn't like the food, and it wasn't as good as all other business class that I'm using

I'm flying several times per month in business class. You had the worst food by far from any company I have ever flew with. The Spanish wine was great. I purchased Internet, but it didn't work well for most of the flight.

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.

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.
