The former flag carrier, which was acquired by the German financial fund 4K Invest in 2016, has been having financial trouble for some time now, and will have to be recapitalised if it does not want to lose its licence.

Recently, the German owners promised to raise the capital by EUR 10m before the end of the year, but Adria is expected to end another year well in the red. The carrier posted a net loss of EUR 5.4m in 2017.

According to EX-YU Aviation News, Adria advertised flights to Bucharest, Kyiv and Warsaw as recently as two weeks ago, when its winter schedule came out, but the routes have disappeared from an updated press release.

Originally, Adria was to fly to Kyiv and Warsaw three times a week and twice a week to Bucharest. Following the cancellation of the routes, Ljubljana Airport will no longer be directly connected with Kyiv and Bucharest, while the Polish flag carrier LOT will continue to fly between Ljubljana and Warsaw.

Adria agreed to wet-lease several aircraft to various airlines, including its three Airbus A319 planes to Germany's Lufthansa.
