The food was delicious. There has been a major improvement here in the last few years. Excellent, friendly service. An enjoyable experience.

Late, dirty cabin, charging ports broken, uncomfortable, no tomato juice, barely edible food

The crew was friendly, and the flight landed on time

Positive: It was refreshingly easy and polite check-in and boarding staff. Flight was on time and Helsinki is a very well-signposted airport. Shopping was nice as well. Flight was not full and I had lots of space in economy. Flight was perfectly on time. Negative: Food and drink not very good, but that it is normal on any airline. Didn't expect anything else.

Very good seat, very comfortable, good food, and good service.

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Our previous flight was delayed but they waited for us to board.

No control at all at the gate , passengers were not cuing up, , some were very loud , no action taken by the attendants . It looked more like a heard of animals then humans boarding a plane .

The entire experience in Turkish business class was superb. From the friendly greetings including the chef, to the polite and classy service, all was wonderful. The in flight entertainment is one of the best. The food was the best I’ve had inflight.

The local Turkish Airlines staff in Helsinki isn’t not aware of immigration laws of Singapore and wanted to refuse even our first boarding and threatened us with deportation on our own from Singapore. We had the next connection to Istanbul and then Singapore. The airline’s online check in system is requesting the visa to download and doesn’t have any option for 96 hrs VFTF passengers. So in general we made the complaint to the airline, as the boarding experience was awful due to unprofessional staff that doesn’t check or want to check the exceptions in the global system.

Majority of the staff were simply awesome and very very supportive and helpful

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

This time my experience was very bad. The Turkish Airlines changed my flight from Erbil to Istanbul from 8:15 AM to 11:20 AM few days before the trip. This made my transit in Istanbul about ONE hour. I have a special needs child and need extra time to navigate the huge new Istanbul airport with a child. To make the matter even more stressful the flight took off about 20 minutes late from Erbil which made our transit even shorter (around 40 minutes). The Turkish Airlines failed me on too many points despite clearly asking for help and as follows: 1. I asked the checking agent in Erbil for seats at the front of the plane to exit first and he stated the closest one is in the middle of the plane and I should ask the flight crew for help 2. I asked the boarding agent in Erbil to ask the flight crew to let us out first since we don’t have much transit time and she said she can’t and they wouldn’t listen to her anyway. 3. When we boarded I specifically asked the cabin crew chief the same request and after some discussion he wanted to get rid of me and said, they will help when we land. I again politely reminded the same person to help us when we exit before landing and this time he stated he would NOT be able to even announce to the passenger to let the people which short transit first and I should just deal with it like other passengers. He also told me to ask for help from the airlines staff at the gate when we get to the airport. This is very rude coming from the Cabin Crew chief. 4. I asked the airline crew at the gate which he had a cell phone to call the gate of my flight to inform them we are on our way and the agent pretended he didn’t speak English… Frustrating 5. I went to the Golf Card station (used to transfer passenger in the large airport) and asked for a ride and the driver there “shooed” me away pretending he doesn’t understand English while looking into his phone constantly telling me “Go this way, Go this way”. I saw first-hand other well able passengers on these cards and Turkish looking families get help on our way … which is clear discriminations. 6. We finally got to the Gate as one of the last people and we didn’t even use the bathroom on our way and made it back to Canada. I am extremely frustrated with the TKY this time and feel discriminated against just because I look from the Middle East despite I am and my child are Canadian. The Turkish Airlines operations failed me on too many points this time.

Four of my family members was settled in a different seats. I paid extra $200 dollars for 4 seats just to be all together, but they settled us on separated seats. After a lots of time they put us 2 and 2. My kids are 9 and 13 . How i can leave them alone???

The airplane from IAD to Istanbul was too old. The chairs were to tight and uncomfortable. I continued my travel from Istanbul to Bangkok. This airplane was better and newer than the first one. Even food was better.

They use a smaller international plane and quarters are tighter, space smaller, and the flight is still 12 hours, then fight attendants are ruff, food is bad, cherry juice spilled by flight attendant and she comes back to ask why have we not changed yet could it be we didn’t have any clothes to change into and seat is all wet and we had to sit there for 12 hours

Service et qualité. Retard départ vol cdg ist, baggage n'a pu arrivé. Temps de transfert très court. Livré le soir.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

This flight was a very good trip for us. The crew were very friendly and helpful. They made arrangements for my husband to have assistance in boarding. We were not expecting a meal, so it was a pleasant surprise on this short flight to have a meal and beverage from a very courteous crew.

I prebooked a comfort plus seat on this flight and therefore the flight was comfy. I got the correct seat in the correct section of the plane that I have booked, that's this. Flight was comfortable. Staff were average on the flight, appearing to be rushed and short in engagement with travellers, perhaps this to maximise there rest time on the flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Very unimpressed that I was dumped from the seat I had booked and paid for after check in. Apparently a family wanted to sit together, however as they all were adults I think they should have pre booked their seats like I did. I will be approaching Qatar for a refund. That and the dreadful state of the flooding toilets made me wonder how they managed to be voted the best airline. Not worth the money.

Doha airport is huge , takes long time to reach gate .

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

Flight was fine overall. What you would expect from economy seats. I did appreciate the amenities (eyemask, earplugs, small toothbrush and toothpaste, thin socks).

The qatar airways flights were great, the code share with Indigo could have been a lot better. There is no option for web check in, there is not information on the tickets for the INDIGO PNR this caused a problem with security letting us into the airport. The indigo staff did not even want us to line up before they opened the counters. There is not option on the indigo flgith to request special meals.

My Tv don’t work the whole from Doha to New Delhi. Overnight didn’t work from Bos to Doha and had to eat food without light
