Airport Regions Council (ARC) - formerly known as Airport Regions Conference, is an association of regional and local authorities with an international airport within or near their territories, founded in 1994. Currently, the ARC has more than 30 members, ranging from regions hosting the largest hubs in Europe (e.g. Frankfurt, Madrid, etc.) to small regional airports (Oulu and Iasi). The governance structure of the organisation includes an Executive Committee (the President and 7 members), an Assembly (ARC member regions) and a Secretariat, which is based in Brussels, Belgium.
