Questionary would have N/A available, I did not eat, can't say I'm either sad or happy with that.

budget airline, you get what you pay for but pilots flew great, crew was awesome!

I mostly blame the dreadful Berlin airport, not Norwegian, but we departed in the rain after trekking for a mile to get to the gate, carrying everything including our baby and luggage down a couple flights of stairs and then walking to the plane on the tarmac in the rain and climbing more stairs to enter the hot airplane. The flight itself was fine, but sitting in the cramped chair, soaking wet, baby in lap, also wet, was hard to overcome.

Delays, uncomfortable, and no compensation or free water after being stuck in the plane for more than an hour!

Flight was 1 hour late. The luggages also arrived 45 minutes late.

Ticket desk was really helpful in resolving issues with ticket machine. Reception staff were less than helpful.l and grumpy when issues were highlighted.

The flight was delayed by 1.5 hours & the gate was changed, so it was a long walk from the 1st gate to the 2nd gate. The bags took about 1 hour to arrive after landing. Ridiculous wait for bags for which we paid extra $$$$$$$

The upholstery of our seats (7A+7B) were in bad shape: twisted, hard and uncomfortable. We also had a 55 minutes delay. Apart from that everything was OK.

We arrived on time to our destination and the flight was peaceful (and short!.)

30 minutes late as usual. Could not pay for any food or drinks, despite using three cards. Amex, Mastercard and Visa. Uncomfortable seats

budget airline, not a lot of amenities but perfectly priced for a 3.5hr flight. Crew/Pilots were great, communicative, and overall provided a great experience for the price point. Have flown with Norwegian when coming in/out of Norway for the past x10 years now!

Unfriendly staff at boarding gate. Unclear announcement at about gate change. Low cost airline with no amenities on board. Bring your own water.

Terrible communication about cancellation of flight. Put on a flight the day after our departure day even though there were seats the following day

…not even a power outlet. Nothing but uncomfortable seating with unhelpful staff.

Overall flight was fantastic.i really enjoy the whole journey .

Little more legroom would have been nice. But it's a very short flight, so it was fine really.

Short flight, some waiting to board, but no issues and no frills.

No staff at the gate and the flights were not posted on the board so we missed our flight. Horrible experience. Be VERY careful flying Norwegian. Super limited ability to communicate with their slim staffing and restricted hours.

Tickets were cheap but it says no where that food was not included, I travel Austrian, Swiss and Turkish airlines all the time always food is included, never flew Norwegian again

Great if not for the boarding by bus at Heathrow terminal 3. Medieval disappointing time-consuming and very hard on handicapped flyers. It was awful

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.

Business seating is soooo uncomfortable. You can sit straight up or lay down. You need pillows behind you because the back doesn’t lay down. Those are need to “prop” you up. The chair has no padding whatsoever. Food was gross. I’ve eaten on Finnair before and the food was exceptional. This time it gave 2 people in our party diarrhea. It was the chicken dish. I took 2 bites and didn’t eat anything more. The flight attendants were nice. You needed an additional lounge in Terminal D at DFW Airport. After waiting 40 minutes to enter, we finally gave up and went to a bar across from the club doors. I’m unsure if I’ll ever book a Finnair flight again.

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

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

The worst with the trip was the space in economy, my knees are still hurting. There was no way to control personal air by turning a knob above you, it was way to hot on both rides. During the night flight they allowed 2 people from across the aile which was narrow to sit and talk for 7 hours while also using tablets and the flashlight from their phones pointing into the row where I sat at times. They allowed people with way too large baggage to bring onboard. I paid way too much for the ticket ($1,364} for economy. Kayak misinformed me to get cancellation insurance that was only valid for a very short time (less than 12 hours) and was over one hundred dollars. Hotel booking was incorrect, I had the room booked myself at the hotel, only double or larger rooms available which I paid over 400 dollars for. I will never fly with SAS again unless there is no other alternative.

Crew members were excellent. The seat wasn’t the best as well as a food options.

Really good. Everything went smoothly. That's what I hope for when I'm on a long flight, especially with multiple changes. Thank you SAS.

Curious and efficient service ! First time flying with SAS and very pleased!

Very uncomfortable and cramped seating. Only 1 bathroom for entire economy section, most of the plane. No food provided for a 5.5 hour flight. Bad experience

The crew was friendly, the flight was pleasant. Thank you for your service!

Our trip plan from Kayak stated we were flying SAS. That was not true. The first leg was a Delta flight. We wasted 25 minutes before finding out to check in with the correct airline. Then our SAS flight for the second leg arrived 25 minutes late, and our third leg flight with SAS closed the gate knowing the flight delay was SAS’s fault, and that this flight would only be backed up 5 minutes. The final kicker was that between Delta and SAS, they lost all our checked luggage.

Ancient aircraft (busted armrests, poor cabin temperature with no option for passenger control). Garbage everywhere. Risible checking of safely conditions on landing. Also, late.

Excellent service throughout. Airport process is quick and easy. Very courteous staff. Great service in the plane! Just outstanding punctuality and service overall!!

I have paid for extra legroom on my flight. My seat was broken and did not recline. The crew could not fix it and refused to provide me with another seat

I need assistance and I could not fault it at all. I suffer anxiety and I was always put at ease by assistance staff, and the banter was good. On board the staff was so very nice and kind and showed empathy. Thank you to them. It was my first time travelling since I lost my husband and was so grateful to them.

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

Buy-on-board through the app is a great feature!

Rubbish moved my seat don’t know why same seat configuration cost me extra so me and my wife could sit together now I know why no paper ticket so they can do this

Take off was great but landing is always with a bump.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

The flight was 1h delayed. There was a flight attendant making announcements in the cabin, but it was impossible to understand whether the information was important or not. (Although whatever she was saying, it was clearly meant to be communicated to the passengers.) From the way she spoke, it sounded like Spanish, but only thanks to catching one word out of every five or six — mumbled through her teeth — I realized she was actually speaking English. It was quite embarrassing

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.
