Air-Britain, traditionally sub-titled 'The International Association of Aviation Enthusiasts', is a non-profit aviation society founded in July 1948. In April 1968, the association was incorporated into a company limited by guarantee, Air-Britain (Historians) Ltd. With over 4,000 members worldwide, Air-Britain publishes books about worldwide civilian and military aviation, that are sold via bookshops, air show stands, mail order and via a secure sales website. Four regular journals are published, with coverage of both current and historical aviation themes. Air-Britain periodically organises events such as aircraft fly-ins and aircraft recognition competitions.
On 16 April 2015, the status of Air-Britain changed from a Private company limited by guarantee, in the form of Air-Britain (Historians) Ltd, to a British charity, in the form of Air-Britain Trust Ltd.
