GuardAir AS was a Norwegian airline which operated between 1992 and 2001. Based at Sandefjord Airport, Torp, it operated four Dornier Do 228s and served eight scheduled destinations in 2001.
The airline was established with a Cessna 210 to search for stolen vehicles. After merging with Wing-Tech in 1997, the airline procured a Do 228 and started flying newspapers. Its first scheduled service connected Skien with Oslo, but lasted only year after the October 1998 start-up. The airline then flew flights from Sandefjord to Ålesund, Kristiansund and an international route to Gothenburg. GuardAir won a government contract to fly to Røst and Fagernes from 2000. Finally the airline established a route from Trondheim to Ålesund and Kristiansund. The airline lost an accumulated 30 million Norwegian krone and filed for bankruptcy on 2 April 2001.
