Is Etihad Airways about to take control of Air Berlin?

Abu Dhabi-based Etihad Airways could be poised to take control of European budget carrier Air Berlin, in which it already has a major stake.

Air Berlin was due to publish results on Thursday morning, but has postponed the announcement pending talks on "strengthening its finances".

A deal with Etihad would be the latest aggressive move by the Gulf airline into the European market - a trend that has European rivals increasingly worried.
