Norwegian is not the main airline of Norway (that would be SAS in conjunction with Sweden and Denmark). Norwegian is (was?) a low cost airline that expanded too fast and used various subsidiaries to incorporate most of their airline in other countries like Argentina or the UK. They have very little in actual assets, they’ve been hurt three times over by 787 engine issues, the 737 MAX, and now COVID, and now their creditors are taking whatever scraps are left.
