The FT doesn't think there is any truth to that:

However, it does think Norwegian's condition is critical. Here is an excerpt:
Norwegian’s net debt has increased steadily from NKr22bn ($2.3bn) in 2017 to NKr58bn at the end of last year — in large part due to accounting rule changes on leases — just as its equity market capitalisation has plunged to NKr1.8bn. Analysts at ABG Sundal Collier show that its net debt to ebitda (earnings before interest, tax, depreciation and amortisation) ratio is 7.1, compared with an average of 1.8 for European carriers — and just 0.5 for low-cost airlines such as Ryanair and easyJet. Norwegian, like almost all carriers, is taking drastic action. On Tuesday, it announced 3,000 flight cancellations — or about 15 per cent of its capacity between mid-March and mid-June — and warned staff in an internal note “to be prepared for a scenario where we reduce capacity by up to 50 per cent”. Few in the industry such as executives, analysts or investors know how big the knock will be. Analysts at ABG already worried last week that Norwegian could break the book equity covenant on its bonds in the second quarter of this year. They also forecast that its net cash of NKr3bn — compared with revenues of NKr43.5bn last year — could shrink to just NKr880m by the end of June. Mr Lobbenberg said that on his models of falls in unit revenues this year of 3-7 per cent, “Norwegian lives” in each scenario. But, he added: “If it’s materially larger, you do challenge those covenants”. Thus many speculate that Norwegian will need to tap shareholders for the fourth time since March 2018. ABG analysts estimated that Norwegian could have to raise up to NKr3bn, close to double its current market value, to avoid facing the same worries next year.
