The airport is owned and operated by the state-owned Avinor and serves Nærøysund Municipality and its surroundings.

Widerøe flies to the airport with its Bombardier Dash 8 aircraft on contract with the Ministry of Transport and Communications.

[12] Ryum was scheduled to be opened on 1 October 1986, but there was too bad weather that day that the ceremonies could take place, as aircraft could not land.

[13] Rørvik was initially served by Norving, which flew two services with the Dornier 228: Bodø–Rørvik–Namsos–Trondheim and Rørvik–Brønnøysund Monday through Friday.

[20] From 1996, Ryum and 25 other regional airports were taken over by the state and the Civil Aviation Administration (later renamed Avinor).

Four years after the nationalization, the CAA proposed that Ryum and certain other regional airport be closed in an effort to reduce costs, but this was disapproved by the government.

The reason was that there were on average only 17 passengers per flight from Rørvik and Namsos Airport, Høknesøra combined.

[24] Since 2010, Nord-Trøndelag County Municipality has been pressing for an extension of the runway to 1,199 meters (3,934 ft) and construction of a larger hangar.

[25] The airport is located at Ryumsjøen in Nærøysund Municipality,[5] 6 kilometers (3.7 mi) south of Rørvik.
