Norwegian was the first European airline to offer wifi on board. Although it is a low cost airline, you can connect to wifi for free, but only for 15 minutes with limited internet speed. For more information on wifi on board, visit the airline's website: www.norwegian.com
Snacks on board are also charged at regular prices (drinks from 3 eur, sandwiches around 10 eur). Food can be pre-ordered on the airline's website: www.norwegian.com/uk/travel-info/on-board/food-and-drinks.
