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

They lost my luggage and there is no update, no luggage and no hope that they will find it. It has been 26 hours since we landed

My daughter always gets sick when we order the gluten free meal option. Internet didn’t work as advertised.

Nothing to answer your questions appropriately. It was just a 2hrs flight from London Heathrow and we were served a cup of tea only. So the questions about food aren't relevant and also, there's no entertainment on these short haul flights. Overall, the flight ✈️ was okay.

The seat in economy are comfy, with some legroom and shoulder room. The food was above average. The plane was newish.

Excellent crew members, but my seat and food wasn’t the best

All went smoothly. That's what I want on a long flight.

I expected more, but they will nickel and dime you for everything. I did not enjoy flying with this airline.

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

I wish they have given us explanations for the delays. And the rebooking process in Copenhagen was too long. I had to wait about 4 hours before they assign me a hotel. From there the handling process (accommodation, transportation and meal) was excellent.

Since our earlier flight was delayed, we missed this flight and were rerouted on Lufthansa 2 days later.

Boarding was terrible. We were all cooped up in a small, claustrophobic space awaiting to be let out to walk to the plane. Very cramped and very uncomfortable.

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.

Dislike standing for 30 minutes waiting to board. Coffee disgusting, hot sandwich almost inedible. Staff cheerful. Flight early.

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

Easy short trip from Faro to Cardiff. Exceptional staff. Early landing and straight through airport in 15 minutes from touch down.

Shady baggage policy that forces you to pay more money at the gate, even after you checked your bag dimensions during the bag drop. Will never fly again with this airline.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

Delay in boarding with no explanation why. Stood for about 40 mins waiting to board

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

Slow and delayed boarding, including standing outside 15m in -3 temperatures, Late take-off approx 45 mins Very slow bag delivery approx 45 min - no explanation

BA Canceled this flight and put us on a flight leaving Aberdeen at 8:00 PM, delaying our return to the states by a full day. The cancellation caused us expenses in both Aberdeen and London and BA was completely unhelpful on the phone and at the airport.

First time flying with them! Loved it! Specially the schedule from Miami and being able to come back directly to New Orleans :)

They lost my luggage on my way to Namibia (I was unable to review that flight as I was in the bush/off line) It took 3 days to get my bag and I had to pay $375.00 to have it transported to my location as it was over 100 Kilometers from that Airport and the local Airlink carrier would not got that far.

Unable to check in online until the morning of flight. No early baggage check available nor any BA personnel present. Poor customer service.

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

Lady next to me was coughing profusely the entire flight, other lady moved seats because of it, 8 hours of that during an overnight flight is a bit much.

We waited all day on a delayed plane. More than a 6 hour delay which caused us to miss all connections and spend a second full day traveling. Also missed a day of work that i hadn’t planned on.

I liked the air hostesses, but no wifi was available for flight. my original flight was canceled and rebooking was difficult and no reason was given for cancellation. Business class cabin was nice and spacious.

We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.

3.5 hr delay leaving Pittsburgh, notifications for which were incomplete and untimely. Connecting flight was automatically switched to one requiring more than a 30 hour layover! After waiting in a long queue, customer service reduced layover to 11 hours and also set up an earlier standby. The standby had empty seats, but the gate agent couldn't change our tickets! On top of all that my luggage was lost and has yet to even be located, much less returned 5 (FIVE!) days later. Too bad there's no rating below poor.
