The story
The airline was established as Astair Airlines in 1998 and became Interavia Airlines on 18 May 2005. It started regular services from Moscow in July 2005. Interavia Airlines was registered as a corporation with publicly traded stock, with no shares owned by the Russian Government.
Because of financial difficulties, the airline suspended operations on October 9, 2008 and shortly thereafter lost its operating licence. Astair only flew with a few (or one) Yakovlev Yak-42.
