In the course of 1988, the airport company's debt increased from NOK 4.5 to 8.0 million. In mid-1989, Partnair bought 51 percent of Fonnafly. Three months later, Partnair filed for bankruptcy, but Fonnafly continued operations. Partnair was reestablished in January 1990, and the company took over Fonnafly's route from Sørstokken to Fornebu in February. The company was bought by Jon Furdal in May 1991, and from 27 July the company moved its main base from Haugesund to Sørstokken, including 14 employees and three aircraft. At the same time, the airline changed its name to Air Stord.
