Jämtlands Flyg has its roots in the 1954 company Jämtlands Aero (1) and derives out of Jämtlands Flyg & Fiske, which was established in Östersund in the mid-80s and started helicopter operations in 1992. The company offers a wide range of operations throughout Scandinavia, and particularly the mountainous regions of Sweden and Norway. Jämtlands Flyg is specialized in wildlife care, tourism and aerial works such as sling load operations, water sampling and various inspections. Jämtlands Flyg operates out of three bases – Östersund (Göviken heliport is the main base), Hemavan-Tärnaby (Laisholm) and Funäsdalen. It is operating a large fleet of Eurocopter and Robinson helicopters of various sizes.

Jämtlands Flyg is a remnant of the company Jämtlands Aero (1), which was founded by the legendary pioneer Gunnar 'Spökis' Andersson in 1954. The company started helicopter operations in 1962, and gradually sold off all their fixed wing aircraft. After Spökis lost his life in an accident in December 1974 his wife Dagmar took over the company. Jämtlands Aero was kept in its leading position, offering everything from flight school to taxi flights and fishing camps for a decade before it was purchased by Sterner Aero AB. Spökis' daughter Siw and her husband Ulf Grinde continued flight operations with their own company. As the helicopter and ambulance operation was sold to Sterner Aero mainly sea planes and fishing camps remained. The project took off by the name Jämtlands Flyg & Fiske AB in the mid-80s, after a short time helicopters came back into opertaion and it rapidly grew to become one of the leading operators in the region. In the mid-90s the fishing camps and seaplanes were sold off and the name shortened to Jämtlands Flyg AB. From now on the company operates a fleet of just helicopters. In December 2007 Spökis' granddaughter Sara Grinde took over as CEO from mother Siw A. Grinde. In January 2011 Jämtlands Flyg was awarded the honorable title Royal Warrant Holder (Kunglig Hovleverantör) by His Majesty The King. The label is appointed to an exclusive amount of purveyors to the Royal Court of Sweden. Jämtlands Flyg is a subsidiary of Spökis AB.
