In the same month the airline also announced plans to open a new base at Hamburg Airport. The plan was cancelled in October 2012, after OLT Express Germany also announced plans to fly between Karlsruhe/Baden-Baden and Hamburg. Since OLT Express Germany filed for bankruptcy shortly afterwards, InterSky started operating the route in March 2013 on a wet-lease contract with Avanti Air. It stopped flying the route in January 2014 after Germanwings announced plans to start the same route from spring 2014.
