Cimber Sterling (Sønderborg) has filed for bankruptcy and suspended operations in the morning of May 3. The Danish carrier originally founded in 1950 as Cimber Air (Sønderborg) had operated five B737-700s, nine CRJ200s, 6 ATR72-200/-500s and 2 ATR42-500s on a network with a main focus on domestic routes in Denmark but also a variety of other regional routes as well as longer flights to leisure destinations. It had operated from bases at Aalborg, Billund and Copenhagen Kastrup and leaves several key domestic routes in Denmark such as the routes from Copenhagen to Billund, Karup, Rønne and Sønderborg unserved. Its partner SAS Scandinavian Airlines (SK, Copenhagen Kastrup) is also affected as Cimber Sterling operated four CRJ-200s on behalf of SAS on a variety of regional routes from Copenhagen. Cimber was controlled by Mansvell, a Cyprus based investment holding owned by Ukrainian billionaire Igor Kolomojskyj, but an additional capital injection expected in April has not taken place anymore. Mansvell also owns City Airline (Gothenburg Landvetter) and Skyways (Stockholm Arlanda) in Sweden which are not directly affected by the bankruptcy filing of Cimber Sterling.
