LCC Norwegian has rejected industry speculation about the financial sustainability of its long-haul LCC model, arguing that the business case has already been demonstrated. “The model has been proven to work now,” Norwegian CFO Tore Ostby said at the Aviation Festival in London. “We started back in 2013 and in 2015 we had our first net profit for our long-haul operation. Since then fuel costs have fallen. Right now, we are building up and investing in our fleet.
