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 flights were on time and I appreciated that the cabin crew helped passengers with overhead luggage - finding space etc - despite not being paid. Apparently their wages don’t start until takeoff. This makes no sense whatsoever.

It is stupid to have to go to Atlanta in order to get to Rochester NY. I was up for 36 hours because who can sleep on an airplane. I'll next do tht again.

Always a pleasure to fly with WestJet. I am however frustrated about the rising costs. We have started to resort to Ultra Basic fares to afford but really missing the extra bag but too costly.

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.

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.

It was a good flight and we arrived on time, plane was clean.

The flight was fine. Long wait at security and for wheelchair. Got to gate about 5 minutes before boarding

Disappointing flight experience! ✈️ A two-hour delay, insufficient food and drinks, terrible cabin crew, and poor service overall. No toothbrushes or toothpaste provided for a long-haul flight — absolutely unacceptable! Compared with Japan Airlines, the difference in service quality is unbelievable. Overall, this experience was simply not good enough.

It was our first time flying wit Air Canada. I found most everything very good, however, our flights leaving and returning were both delayed. And we were met with no place to de-board the plane and had to wait an additional 45 minutes on the plane after arrival. That was very disappointing. Also hefty fees both ways on what would normally be a carry on bag on any other airline.

Traveling from Montreal to SFO, after landing in SFO, there was no announcement about where to claim our luggages. Our gate was in Terminal 1, and went to the luggage claim area in T1, but couldn't find any information on the screen. Eventually, an airport agent told us that our luggages would arrive in Terminal 2 luggage claim area.

Very good, easy to check in, 24 hours to cancel, good prices, nice flight attendants!

Great flights. Only criticism is when landed I. Montreal, wheelchair service has no signage or anyone letting you know where to go , just an older gentleman at the desk looking confused

This is a regional jet. As far as those go it was average. Again poor quality for an expensive seat. Not worth the upgrade

All went really well. Except that I was randomly chosen to be thoroughly checked!!

We were reluctant to travel with Air Canada after reading many bad reviews; however, we were more than satisfied with the experience flying from San Francisco to Montreal and back. Seats were comfortable (although on the return flight we had very little leg room) and the crew was friendly and competent. The entertainment was outstanding, with hundreds of choices, from movies to shows to comedy. Our luggage was delivered in a timely manner (a little slow in San Francisco) and we were sent tracking notices all along the way through the Air Canada app. I wouldn't hesitate to travel with Air Canada again.

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.
