Airline reviews

I loved the ability to upgrade my seat which was worth it. The large seat and ability to recline made it comfortable to fall asleep. My only two complaints were entertainment (movie selections were old) and approx 30 mins before landing the crew started to collect the blankets despite the cabin air temperature remaining cold. Maybe wait for passengers to get off the plane before collecting the blankets.

Excellent! Although it stinks to pay extra for leg room and then have no screen option.

Very much dislike: Airline requires check-in at the Airport Airline does not work with TSA PreCheck

Overall a great experience. Only complaint was the movie selection was pretty limited, but that's pretty minor in the grand scheme of things and easy to overcome.

The crew was unfriendly front check-in. The filth in the plane was so disappointing. I could smell dirt and looked up and there was literally dirt that was blowing in through the air. Old food on the seat back tray in front of me so I didn’t use it. No toilet paper in the bathroom and scum/old dirt next to the seats.

No blanket pillow headphones, not even a water or snack makes for a very uncomfortable flight. There are too many extra fees that should be basic and standard included.

There was no communication about the check-in process, even the fact that Norse doesn’t do online check-in! And once we were at the Los Angeles airport (LAX), there was no signage or assistance about where to check in. I kept Googling for 3rd party information until I finally found on the airport website that we had to check in at Terminal 1 and be bussed back to Terminal B, the international terminal. How were we supposed to know that?! Otherwise, the flight itself was comfortable and the attendants were helpful and friendly. I just feel like we were lucky to have managed the check-in and boarding process on our own - why keep it a secret??

The flight was comfortable, smooth, hardly any bumps even though we encountered some jetstream. The onboard entertainment could be jazzed up a little, the TV shows were old ans not much variety. The movies we ok. The staff was pleasant. The Orlando ground crew was excellent, they were pleasantand friendly. My kids and I were seated separately but the Orlando crew was able to reassign us together. The ground crew at Gatwick, UK need some work on attitude, they were not so sociable. All in all wonderful flight to and from England. I will be definitely traveling with Norse again. Ps...Norse need to work on an app for both Android and iOS.

Crew at airport who completed boarding were incredibly and blatantly rude and unhelpful. 0/10 customer service. I was going to upgrade my seat to first class and upon asking, I was met with an awful attitude so I changed my mind.

Boarding was a disaster. 2 hours in line to get boarding passes and we had no luggage to check in. Coffee was $4 so is water. 11 and a half hour’s flight and food was not included. You could purchase the food but it was complete garbage, This is worse than spirit airline. Never again
