The low-cost carrier embarked earlier this year on a wide-ranging cost reduction programme, which includes reducing frequencies and cutting routes, selling aircraft and postponing delivery of new aircraft.
It posted a first quarter (Q1) loss on Thursday (25 April) of NOK 1.49 billion (£134 million), a significant increase on the NOK 46.2 million (£4.14 million) it recorded last year.
The airline, meanwhile, has increased its 2019 cost target by “up to” NOK 500 million (£44.8 million).
