InterSky, legally Intersky Luftfahrt GmbH, was an Austrian airline headquartered in Bregenz, which operated scheduled services from its base at Friedrichshafen Airport, Germany, to major cities in Germany, Austria and Switzerland, as well as seasonal holiday flights to the Mediterranean from other airports. The airline ceased operations on the evening of 5 November 2015 due to financial difficulties. History Early years Intersky was established in November 2001 and started operations on 25 March 2002.

InterSky served Berlin-Tempelhof Airport right from the start. When it became known that the airport would be closed at the end of 2004, Renate Moser joined several citizens initiatives to keep the airport open. Together with other airlines, she supported a legal dispute that finally guaranteed this until the end of October 2008. InterSky flew to Tempelhof until the end and on the last day before the closure, they conducted several sightseeing flights to say goodbye to the airport together with the employees. An InterSky aircraft was one of the last machines allowed to take off from Tempelhof.
