Norwegian review by Bernt 2013-06-15

Very little legspace.
Uncomfortable and hard seats.
Often long lines for checkin.
Fares are usually approx the same as full service airlines and you have to pay extra for additional services making the totalfare high.
Plus for free Wifi, if it works.
More delays than comparable airlines in Norway, measured on arrival time which I think is the most important.
All in all, if you have to go Norwegian, if you can choose something else you should. Might work if you fly a seldom time now and then but for frequent flyers not a good option.
