The flight distance between the nearest airports London (LCY) and Paris (ORY) is 218.10 mi (351.01 km). This corresponds to an approximate flight time of 0h 54min. The initial bearing on the course from London to Paris is 148.16Â° and the compass direction is SSE.
The aircraft flew various routes, primarily between London/Paris and the USA but was restricted from travelling at supersonic speeds over land due to the sonic boom it created, which hampered its viability. Flying at an altitude of 60,000 feet, the delta-wing Concorde achieved speeds of mach 2.04, almost 2200 kph. While conventional jet-powered aircraft took eight hours to fly between Paris and New York, Concorde slashed that to just under 3.5 hours.
