Dan-Air was a British airline established in 1953 as a subsidiary of Davies and Newman, a London-based shipbroking firm. It began with a single aircraft and initially focused on cargo and passenger charter flights. Over its 39-year history, Dan-Air expanded significantly, becoming Britain's largest independent airline by the mid-1970s in terms of passengers and fleet size. The airline was an early adopter of jet aircraft in Britain, introducing de Havilland Comet jets in 1966 and becoming the first British operator of the Boeing 727 trijet in 1973. Dan-Air operated a diverse fleet for inclusive tour charters, scheduled services, and oil industry support flights, with hubs including London Gatwick and Berlin–Tegel. Facing financial difficulties, Dan-Air ceased operations in 1992 and was acquired by British Airways.
