By Reuters Staff (Adds CEO, background) OSLO, April 12 (Reuters) - Norwegian Air has won approval from creditors in Norway to restructure its debt and an Oslo court has approved the plan, the airline said on Monday, clearing the way for it to raise new capital and emerge from bankruptcy next month. Financed largely by debt, Norwegian Air grew rapidly, serving routes across Europe and flying to North and South America, Southeast Asia and the Middle East before the COVID-19 pandemic plunged the airline into crisis. Its survival plan announced last year brings an end to its long-haul business, leaving a slimmed-down carrier focusing on Nordic and European routes.
