Norwegian Air was given additional creditor protection by a court in Norway today on top of that granted by an Irish judge yesterday.
This will allow the cash-strapped airline's restructuring efforts to continue.
"A supplementary reconstruction process under Norwegian law will be to the benefit of all parties and will increase the likelihood of a successful result," the airline's chief executive Jacob Schram said.
Norwegian said it could now move forward with the dual-track process.
The company helped transform transatlantic travel, expanding the European budget airline business model to longer-haul destinations.
But it has been forced to ground all but six of its 140 aircraft amid the Covid-19 pandemic.
If successful in convincing creditors and owners of its future potential, Norwegian could, with the help of the courts, emerge as a smaller but more efficient carrier with fewer aircraft, less debt and more equity.
"Our aim is to secure jobs in the company and to contribute to securing critical infrastructure and value creation in Norway," Schram said.
The airline, which has said it could run out of cash by the end of the first quarter of next year, aims to complete the debt restructuring by February 26.
While Norwegian's major aircraft-owning subsidiaries are Irish, the parent company Norwegian Air is registered in Norway, and the company had told the Dublin court it could seek additional court protection.
"We will now concentrate on working towards our goal of reducing company debt, reducing the size of our aircraft fleet, and ensuring that we are a company that investors will find attractive," Schram said.
"We will be ready to meet the competition for customers after the Covid-19 pandemic," he said.
The High Court in Dublin yesterday said it had agreed to protection for both Norwegian Air and its Irish subsidiaries as the entities were dependent on each other for survival.
After growing rapidly to become Europe's third-largest low-cost airline and the biggest foreign carrier serving New York, Norwegian's debt and liabilities stood at 66.8 billion crowns ($7.64 billion) at the end of September.
The company's proposed rescue plan includes the conversion of debt to equity and the raising of up to 4 billion crowns from the sale of new shares or hybrid instruments.
Norwegian's shares rose by 22% in Oslo today but are still down 98.8% so far in 2020.
