Kallax Flyg is a large utility company that operates out of several bases spread throughout large parts of northern Sweden. The company has a large fleet of Eurocopter and Schweizer aircraft, which it uses for everything from tourism/taxi flights to sling-load operations and reindeer mustering, including a seasonal shuttle-traffic between Nikkaluokta and Kebnekaise each summer. Kallax Flyg has its main base and technical department at Långnäs Airfield in Piteå. It's got two hangars in Kiruna, one in Lycksele, one in Arvidsjaur and one in Alta (Norway). The company offer a wide range of flight training in Piteå through the flight school Proflight Nordic AB. Proflight has a deep-rooted cooperation with Roslagens Helikopterflyg and Kallax Flyg, which grants the accessibility of several helicopter types, including Enstrom aircraft, Schweizer 300s, Ecureuils, Colibris, Jet Rangers and Long Rangers.

Kallax Flyg AB was established by the Stenvall family back in 1998. The company is a subsidiary to Stenvalls Trä AB, which is a large Swedish wood company. In early-2004 Kallax Flyg purchased Norrlandsflyg's utility activities in northern Sweden, and four of its helicopters. Norrlandsflyg had decided to focus on its EMS and SAR activities instead of the utility work. Kallax Flyg purchased the maintenance company Helimek AB the same year, which soon became the core in Kallax Flyg’s in-house maintenance organisation. Kallax Flyg purchased the Kiruna based Polarhelikopter and its two helicopters in 2005. In 2008 the company became the first operator of the modern EC 130 (SE-JOX) in Sweden.
