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 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.

I paid $150 to upgrade to this seat. My exit row seat had ample leg room BUT the collapsable table was broken so my food tray and drinks slid over to my lap, the screen malfunctioned.

I really enjoyed the food, only bad part on one of my flights my screen was a bit buggy but it wasn't a big deal it was one of their older planes so I understand that happens

Boarding at Istanbul airport is pretty good. The seats on the A319 are easily the smallest and tightest I’ve ever flown. I’m 1,82m and knees firmly against seat in front of me, as upright in seat as I could get. Very uncomfortable

Awful. They cancelled my seats and demanded $1360 to rebook me

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

It was a terrible airline. The air hostess and the people in the flight, just very rude.

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

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.

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

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).

Boarding process was terrible. Will not travel Qatar Airways if I had an alternative. The food was one of the worst, even for airline food.

Ambience of the aircraft was great. Spacious seats with sufficient leg room in economy class. The layover could have been shorter.

Bag check in at DC was slow. Boarding process was slow more due to customers unfamiliar with how to board properly. Food and service was excellent!

The flight was mostly good, but I sat next to a couple of passengers who were semi unpleasant. We sat next to the emergency exit. One man was drunk and when he got up to get something from the overhead compartment, he tripped and fell on me while I was sleeping, waking me up. The other man seemed sick as he was sneezing a lot and clearing his throat and nose often. This made the flight a bit unpleasant unfortunately. Otherwise I’m usually very happy with QA. Thanks
