Well they will get a brand (at least the 'baby' part) that is very well know in the areas they operate and generally a now respected one.
Fully trained staff from frontline to back office.
A fleet of aircraft (owned or not, it is still a fleet that would otherwise, from a start-up perspective, be needed).
Probably most of all an air operating license.
The only thing I can see is that they will have to find a new head office/operations centre... I believe their old 'Tinytown' is still available?
