Greek regional airline Astra has cancelled all flights amid speculation that it has financial struggles.
The airline has not commenced any flights since 9 November, it had hoped that a bailout from the Greek government would help - but it hasn't.
Local reports suggest that in order to remain in operation, the airline is looking for a new investor to provide funding - this looks doubtful because of the large amount of competition in the Greek market.
Speculation suggests that Astra may be forced to cease operations permanently.
Astra was co-founded by Ioannis Zlatanis, founder of Interaviator Ltd, and Anastasios Zirinis, former CEO of Olympic Aviation. It launched its operations on 5 July 2008, and has a small fleet that consists of two ATR 42-300s, one ATR 72-200 and one BAe 146-300.
