Air Berlin

Etihad announced on Tuesday that the company was "informed that Air Berlin has filed for administration."

“This development is extremely disappointing for all parties, especially as Etihad has provided extensive support to Air Berlin for its previous liquidity challenges and restructuring efforts over the past six years," a statement said, and added:

Pegasus Airlines has reached an agreement to buy Air Berlin's 29.51 percent of stake in their subsidiary İzAir for 1.2 million euros, the carrier said in a written statement late on March 8. 

The share of the company in İzAir will increase to 98.63 percent after the deal is finalized and approved by authorities, according to the statement to the Public Disclosure Platform (KAP). 

German airline Lufthansa said on July 30 it saw no let-up in the pressure on fares in Europe, mainly as budget carriers like Ryanair move in on its home market.,

Bulgaria Air has released cheaper plane tickets to Germany's Dusseldorf and Russia's Moscow.

Starting June 1, the aircrafts headed from Sofia to Dusseldorf will have a limited number of seats available at a price of EUR 65 for a one way and EUR 130 for a roundtrip.

Direct flights to the German destination will be operated every Tuesday, Thursday and Saturday.

Airlines rushed on March 26 to change their rules so as to require a second crew member in the cockpit at all times, hours after French prosecutors suggested a co-pilot who barricaded himself alone at the controls of a jetliner had crashed it on purpose.
