British Island Airways plc (BIA) was the legal successor to British United Island Airways (BUIA). It commenced operations under that name in mid-1970. Ten years later it merged with Air Anglia, Air Wales and Air Westward to form Air UK, at the time the United Kingdom's biggest regional airline and its third-largest scheduled operator. The first British Island Airways had its head office at Congreve House (1970–1972) and Berkeley House (1973–1979), which are respectively located in Station Road and on the high street in Redhill, Surrey.

In 1982 British Island Airways was reconstituted by splitting off the charter operation Air UK had inherited from BIA at the time of its creation into a separate company.

The reconstituted BIA ceased operations in 1991.
