Adria Airways plans to turn its three weekly flights from Ljubljana to Berlin, which it launched last April, into a seasonal summer service only. The flights are expected to operate until the end of October, after which they will be temporarily cancelled until next summer. Eralier this year, Adria terminated flights to Istanbul and Stockholm and cancelled plans to launch operations from the Slovenian capital to Cologne. The Slovenian carrier has seen its passenger number fall 9% from Ljubljana, which had a knock-on effect on the airport's performance. "Adria will obviously first consolidate its existing network and later consider new routes from our airport", Ljubljana Airport's Head of Airline Management, Janez Krašnja, said. Earlier this year, the Slovenian carrier was purchased by the German turnaround fund 4K Invest.
