Norwegian Air Shuttle reported a widening first-quarter loss and said it was still assessing the financial impact of the grounding of the Boeing 737 MAX, but that it could cost it up to NOK500 million ($57.5 million) in 2019. Norwegian posted a net loss of NOK1.49 billion, compared with a NOK46.4 million loss in the year-ago quarter, and said it would consider changes in its narrowbody fleet in 2019 “given the unresolved situation with 737 MAX 8 worldwide.”
