And crewed by whom and on what AOC? Good luck getting CASA to allow a new type flown by noone with type experience.
So you are assuming the NEO is a new type? Plenty of A320 type rated pilots were just made redundant by Tiger.
They would buy the Tiger AOC and slots of the Administrators.
For about the fifth time, it is not possible to purchase an AOC. It is possible to purchase the company that owns the AOC which then means you take on the liabilities of that company, unless there is a DOCA formulated under administration which reduces any liability as agreed by creditors.
