The deregulation of air traffic services (ATS) at Swedish airports has taken off well and since the end of 2013 the private Swedish company ACR Aviation Capacity Resources is now operating the control towers at nine of the country’s 36 airports. ACR more than doubled their business when the company took over the towers at the airports in Kalmar, Jönköping, Norrköping, Karlstad and Skellefteå on 1st January 2014.
