I think flatlander gave a great answer.

In my opinion I think Norwegian have a sound network and structure as well as brand recognition. The only way for Norwegian to demise in this winter is a catastrophic event. Personally I think provides nothing else changes, Norwegian can have a good operation for at least 2-4 years ahead. The future of Norwegian can be told once the critical 2-4 years passed. It is important for Norwegian to mature after expansion in recent years. Norwegian can be walking along the boarder line of being financially health for the coming 2 years and once it pass this stage we should know better (the situation). I just do not see it going bust during this period.

That being said, I am not convinced on their BKK and SIN routes performance and future. And I don't see their current route structure could survive in the long run without a partner in the USA. The Argentina operation is untested which could lead to future bleeding.
