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

As always, it’s a pleasure to travel with KLM. It is one of my favorite airlines.

Brand new plane lots of room the snack was very flavourful and enjoyable

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

There were no charge points for phones on the economy seats. The seats were comfortable overall. Food was okay.. flight was on time

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Flight was on time, staff are friendly and helpful onboard.

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

Didn't manage to get luggage on the plane to Bari. The luggage was checked in all the way to Bari.

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

Upon departing and landing, the man seating in front of me had his seat leaning back. Taking off nobody told him anything. Landing someone from the crew said something but the passenger ignored him and nobody followed up. Felt a bit unsecured. If this that is some of the basics are missed, what else was overlooked?

On time, reasonably comfortable for economy, decent food. All in all a very good experience.

Every flight got canceled or delayed. Customer service was awful.

Flight was cancelled without notice or any reason given. I found out coincidentally when i was checking the baggage allowance on the app, When contacting the airline, the only option peresented to us meant we lost a day of our weekend getaway. Had a lot of contact with airline prior to flight, trying to get them to resolve the issue. We could have traveled the first stretch ourselves but the airline refused to accommodate this. The airline outright refused to be forthcoming in agreeing to alternatives that would let ut keep the date we had booked, and so a third of our holiday effectively vanished. This meant a lot of hassle, changing hotel nights, activities etc. Furthermore and after the flight, customer service refused to answer our complaint unless we used their very restrictive online form, which gave us no chance to properly explain what our issues were. They have of course denied our complaint, and so i have to bring the matter further. If you have an alternative airline to use, please do. SAS treats its customers as a necessary evil.

The two transatlantic flights we took on Scandinavian, between Los Angeles, and Copenhagen, were significantly less enjoyable than other SAS flights we have taken, particularly within Europe. The flight attendants seemed overworked. There should have been more attendants servicing the plane. The food was particularly disappointing. Lettuce on the salad was frozen. A snack of a tikka masala pita was less than tasty. The flights did leave and arrive on time.

They lost my luggage and can’t find it. My trip is ruined. Online tracking of lost luggage doesn’t work

Flight attendants were attentive and friendly. Enjoyed the peppered shrimp snack. Check in was easy. Only negative was the time it took to get checked luggage, but that was the slowness of CPH staff.

Better food; taste, portion. Bottle of water per seat was great.

Excellent business class seats, service and food. No airline does it better.

The only negative thing was boarding a Copenhagen-bound flight in Toronto. The middle aged woman at the desk gave me some bad time, claiming they wouldn't allow me to board the flight, switching to russian in the process. After I asked her to speak English and explained her that I had to reroute with the airline due to flight cancelations that where beyond my contro and will be leaving the Shengen zone promptly, she told me I had to check in my small bag because the flight was full and they needed someone to give up their cabin luggage. After I refused, she told me she would have to check my bag if it fits the allowed dimensions, which it did. I understand she's not an SAS employee, I understand she needs to check the documents and also make sure there's enough room for overhead bags on a plane. What really made me mad was her hostike tone and the beyond poor communication skills. Basic politeness would go a long way.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Just pushing back from gate now. Boarded into fourth aircraft with 13 hour delay to scheduled departure. Crappy experience.

Notified as to why there’s a delay with our flight.

I didn't eat any food so can't comment on that. The prices on the plane are extortionate (as are all prices on planes). Everything else was seemless and a great experience

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.

Waiting outside for a long time is not really necessary

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

I had heard horror stories about Ryan air and was a little worried about my flights with them but I had 3 flights with them in Italy, Puglia and Sicily and it was a painless and smooth process. I was very happy.

Ryan air flight was good. Nothing to complain about. I had heard absolute horror stories about Ryan air so was worried about the flight but everything went smoothly. We have had two Ryan air flights with no problems. Last flight is Vernon come. Palermo to Milan. Fingers crossed.

From boarding to disembarking, the whole operation was very efficient.
