There are NO supersonic aircraft flown by Air France and British Airways.
However, up to 26 November 2003 they both flew the Aérospatiale-BAC Concorde.
I believe by reading an article "THE AIR FRANCE BRITISH AIRWAYS SUPERSONIC CONCORDE AIRCRAFT FACTS HISTORY INFORMATION AND PICTURES", that a Supersonic Concorde was first introduced in January 26, 1976 and it was first fly in March 2, 1969.

Mainly British Airways and Air France operated the majority of Concorde's with Singapore Airlines sharing one with British Airways and Braniff International Airways leasing 10 Concorde's (5 from BA and 5 from Air France).
The Concorde was a supersonic passenger airliner. It operated with British Airways, Air France and for a short time Singapore Airlines.
British Airways and Air France exclusively flew this aircraft.
The national airlines of the two countries that built it - British Airways and Air France.
Not a person... it's a joint design by Britain and France: combining the manufacturing efforts of Aérospatiale and British Aircraft Corporation
France and EnglandThe Aérospatiale-BAC Concorde is a turbojet-powered supersonic passenger airliner, a supersonic transport (SST). It was a product of an Anglo-French government treaty, combining the manufacturing efforts of Aérospatiale and the British Aircraft Corporation. First flown in 1969, Concorde entered service in 1976 and continued commercial flights for 27 years.Among other destinations, Concorde flew regular transatlantic flights from London Heathrow (British Airways) and Paris-Charles de Gaulle Airport (Air France) to New York JFK and Washington Dulles, profitably flying these routes at record speeds, in less than half the time of other airliners.With only 20 aircraft built, their development represented a substantial economic loss, in addition to which Air France and British Airways were subsidised by their governments to buy them. As a result of the type's only crash on 25 July 2000 and other factors, its retirement flight was on 26 November 2003.Concorde's name reflects the development agreement between Britain and France. In Britain, any or all of the type-unusual for an aircraft-are known simply as "Concorde". The aircraft is regarded by many as an aviation icon.
