While Adria did not specify for the STA which additional flights it has planned, the daily Delo reported last week that the number of flights to Warsaw would increase and more flights on the Prishtina-London, Tirana-Munich, Lodz-Paris and Olsztyn-Berlin routes were planned.

The scrapping of the flights to Berlin's Tegel airport, which were introduced in April last year, comes after flights to Stockholm were scrapped in April.

Adria also decided not to go ahead with the planned launch of scheduled flights to Germany's Cologne in late April.

In the first five months of the year, the number of passengers of Adria, which passed into majority ownership of the German 4K Invest fund in mid-March, dropped to 381,300 from 418,122 in the same period last year.

The company attributes this to a drop in the number of winter charter flights to Egypt as a result of terrorist attacks.

Adria's last year's results are to be published in the first half of July, but media have reported the company generated a loss.

Adria has been undergoing restructuring since its ownership changed, including by reducing the number of employees.
