Niki is an interesting one. It was reported to have been sold to Et.had, in return for further much needed cash, which raises some possibly awkward questions about non eu ownership. But now that Easyjet has an austrian AOC, they as well as TUI may very well be interested.

Etihad own only 25% if Niki, wonder where the $320M has gone in Air Berlin, have they burnt through that so quickly?
