British Caledonian was a private, British independent airline, operating out of Gatwick Airport. It came into being in November 1970 when the Scottish charter airline Caledonian Airways, at the time Britain’s second-largest, wholly privately owned, independent airline, took over British United Airways, then the largest British independent airline as well as the United Kingdom’s leading independent scheduled carrier. The BUA takeover enabled Caledonian to realise its long-held ambition to transform itself into a scheduled airline.
A series of major setbacks during the 1980s as well as the airline’s inability to grow to the minimum size led to increasing financial difficulties during the second half of that decade. This was the time the airline began looking for a merger partner to improve its competitive position. In 1987, British Airways gained control of the airline.
