I recently flew Norse Atlantic Airways from JFK to Oslo. It was about 2 weeks after they started their flights. They still have some bugs to work out. Late leaving JFK to Oslo & late leaving Oslo to JFK. You do pay for everything. If you want to check in at the airport there will be a fee. If you want to place your bag overhead rather than under your seat, there’s a fee. When I few (4th of July weekend) there was no WI-FI on board. I flew economy light (only had a backpack) from JFK to Oslo and upgraded on flight home to premium. I personally will book premium in the future because I prefer to have more space on longer flights.
