Slovenian flag carrier Adria Airways has filed for bankruptcy, after financial pressures led to days of disruption to its flight schedule.

The airline says it has filed with the Carniola district court.

Adria had been planning to operate several services on 30 September, having been largely inactive for the past week, but the official departure information for Ljubljana airport shows its flights have been cancelled.

“Bankruptcy proceedings were filed by the management of the company due to the company’s insolvency,” the airline says.

The court has three days to decide on the opening of bankruptcy proceedings.

Adria also confirms that it will halt all scheduled flights as a result of the bankruptcy petition.

It had been ordered on 30 September to stop using another Bombardier CRJ900 in its fleet following termination of the lease.

The Slovenian civil aviation agency says it has informed the carrier that it has been formally delisted as the user of the aircraft, registered S5-AAK.

Cirium fleets data shows that the aircraft, MSN15128, is leased from AeroCentury.

Two other CRJ900s used by Adria – registered S5-AAU and S5-AAV – have already been the subject of similar cancellation of lease agreements by the entity Trident Aviation Leasing Services.

Adria Airways had also been using Airbus A319s and Saab 2000s alongside its CRJ fleet.
