If Norwegian get anyything from the Norwegian government that can be likened to state aid it will be well hidden and evenhanded.
It could be a general time limited reduction in airport and/or airspace fees, or a way to bypass union rules and faster make people redundant or onto unpaid leave and then immediately give these (ex) employees an increased dole (already done in both UK and Ireland I believe). Maybe some delayed tax for all industries like the fee employers pay for having employees.
They are not about to insert 100 million cash into Norwegian's coffers as a direct handout, because the queue for that line would be long from other travel industry entities like hotels and event organisers plus others that feel they should get some to.
And the Norwegian Wealth Fund to buy up more of the Norwegian's shares to increase the sharevalue would do nothing for the airline's finances, only for its shareholders.
