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

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.

The crew were all helpful, kind, and effective. There could have been more space under the seats.

Bumped from my connected flight, we arrived earlier than scheduled and I was bumped 4.5 hours later. There was no reason, they said my time I wouldn’t have connected in time. I had 41 minutes. None of Westjet customer service in airport could figure out why me and my 5 year old were bumped from flight we booked. We had 10 minutes to get to next gate after we got off the plane, one lady mentioned that’s not enough time to get to next gate. I was there in 3 minutes. Was originally suppose to fly out at 6:50 pm And was re scheduled to 11:45pm.

Everything went well, smooth flight, arrived on time, no lost luggage!

Horrible, delayed 3 hours due to a mechanical issue where the plane is deemed unsafe so we had to deplane after an hour on the tarmac. No credit was given even though plenty of passengers missed their connecting flights and then the baggage claim info showed that no flight was being loaded on the carousel whilst the bags were being dropped, so no one knew if it was the right flight or not since the arrivals screen didn’t show anything.

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.......

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.

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

Flight was re-scheduled for the next day. No voucher for a hotel offered. Boarding was delayed by almost 1 hour. No free meal or even water was offered on board. When tried to purchase a coke, was denied because they didn’t accept coins less than 1 euro denominations. A young male flight attendant was especially rude and unhelpful.

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.

Liked that it wasnt a full flight but we were asked to check carry on luggage as we were told the flight was full so i did, and that was not true. There was tons of empty overhead bins. No entertainment, and only one drinks and snack service when my ladt flight on aircanada in February, Montréal to Victoria had 2 drink service offers in the 5 and a half hour flight. Why only one this time? It felt very "budget" and cheap

Connection was easy to find and quick. Plane was older but comfortable. The food contained beans again so a similar problem of being in a tin can in the sky after eating beans. Overall flight was uneventful which is great.

Enjoyed the A330 comfort, and the inseat entertainment. Horrible disembarking experience. No gate when we landed to sat on tarmac for 40 minutes, and missed my train.

Flying with Air Canada is not pleasant at all. The plane is very old, meaning that there is no on board entertainment, the leg room is less, and it is dirty and in poor repair. To make matters worse, the crew was pleasant enough on my initial fight, but very rude on the return flight. Furthermore, the website advertises many amenities for international flights that are not honored when you were flying from the US to Canada even if your flight is five hours long. Even if you are willing to purchase food, they will likely not have over half of the advertised options available. In addition, you will pay twice the amount of a child’s order for an adult order of same item even though it is the same size as the children’s. It was just really bad on many levels I will try to avoid flying with Air Canada again at all costs

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

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

Overall excellent service and Frankfurt Airport was very efficient and clean

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.

Waiting area not big enough for all the passengers, no airport lounge.

Really appreciated the care, attention and friendliness of cabin crew. Very comfortable, prompt and efficient flight.

People were nice. Seats are so cramped my knees had to be pressed into the seat in front of me.

Dreadfully long wait for bags at Dublin coming off an already late flight.

Flight was delayed and there was boarding pass and flight information errors resulting in confusion and stress

Aer Lingus was the actual airline so they handled everything professionally.

Economy extremely cramped. Dinner was not good. Breakfast was quite good. Crew was excellent.

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.

Excellent service smooth flight f or the most part food was right now.I'm expectedly good.
