"countries who still demand 70%"
What nonsense is this, this is generally government funding furlough payments, companies can't pay what they don't have, but these now can't even get government help the way the company is structured, with the possible exception of the UK part, which can get up to £2500 before tax and NI, which will equal to £1950 or so a month.
All companies have had to come with offers in these times, but NAS never stood a chance, because they simply don't have the cash to sustain it.
If they had not expanded so fast,and rather gone for steady growth, maybe they would have had more cash in the bank, however that is still a problem, and will be a problem again tomorrow and the next day for Norwegian, who now risk becoming a regional airline mostly doing European short haul. 2/3's of the company is gone at the moment.
However if you not employed by the airline, not even being union member can help you in situation like now, divide and conquer. As a professional I call it for what it is, an absolute disgrace, and I feel sorry for all the crews and great sympathy who in many ways was forced over to OSM without any choice of their own a few years back, and who now have suffered this terrible blow.
