A British Airways Boeing 747-400 made a new subsonic speed record for a New York-London flight on 8 Feb 2020.
A 22 year old BA 747 on flight BA112 from New York John F Kennedy airport landed in London Heathrow Airport in just 4h 56min, which is 1h 20min faster than scheduled flight time for the route.
The flight BA112 benefited from the powerful transatlantic jetstream created by Storm Ciara to set a new subsonic speed record.
The previous subsonic record of 5h 13min was set by a Norwegian Boeing 787-9 in January 2018, operating between New York JFK and London Gatwick.
A Virgin Atlantic Airbus A350-1000 on flight VS4 was only 1min slower than the BA 747-400,
However, Virgin says though it was “narrowly beaten”, the 747 had “twice the [number] of engines and burnt twice as much fuel” as the A350 twin jet.
The fastest-ever crossing between New York and London was flown by a British Airways Concorde (G-BOAD) on 7 February 1996, when it completed the sector in a record 2h 52min and 59s. The supersonic airliner had a cruise speed of Mach 2, equivalent to 1,350mph.
