Dan-Air (Dan Air Services Limited) was an airline based in the United Kingdom and a wholly owned subsidiary of London shipbroking firm Davies and Newman. It was started in 1953 with a single aircraft. Initially, it operated cargo and passenger charter flights from Southend (1953–1955) and Blackbushe airports (1955–1960) using a variety of piston-engined aircraft before moving to a new base at Gatwick Airport in 1960, followed by expansion into inclusive tour (IT) charter flights and all-year round scheduled services. The introduction of two de Havilland Comet series 4 jet aircraft in 1966 made Dan-Air the second British independent airline after British United Airways to begin sustained jet operations.
