A blast from the past when British United flew between the UK and Brazil.
British United took over BOAC’s South American routes to Argentina, Brazil, Chile and Uruguay on 5 November 1964. Those routes, flying VC10s via Madrid, Lisbon, Las Palmas or Freetown, became profitable for United by late-1968. In November 1970, the airline was sold and merged into Caledonian to form British Caledonian that continued to fly to South America, replacing the VC10s with Boeing 707s in 1972, which allowed for a non-stop service between London Gatwick and Rio.
British Airways took over the routes from British Caledonian in 1985.
