Intersky was a regional airline based in Bregenz, Austria, operating scheduled and charter flights across Central Europe. Founded in 1998, the airline focused on connecting smaller regional airports with major European hubs, serving business and leisure travelers in the Alps and surrounding areas. The airline primarily operated routes from Friedrichshafen, Germany, and other regional airports to destinations across Europe. Intersky was known for its focus on the Lake Constance region and provided connections that were underserved by larger carriers. Intersky ceased operations in October 2014 after facing financial difficulties and an inability to secure continued funding. The airline's collapse left a gap in regional connectivity for the Vorarlberg and Lake Constance area.
