The accelerated journey also decreased the amount of fuel consumption, FlightRadar24 said.
“The flight took advantage of a well-placed and strong jet stream to reach London in under 5 hours,” FlightRadar24 said.
The jet stream is a core of strong winds, measuring between 5 to 7 miles, that blow from west to east — so, from North America to Europe — across the North Atlantic Ocean. It’s located in the tropopause, above the Earth’s surface.
The subsonic record for the same New York-to-London route — which excludes flights from the supersonic Concorde — was held by a Boeing 787 plane flown by Norwegian Airlines, which took five hours, 13 minutes in January 2018.
Referring to its Saturday flight, a British Airways spokesman told Business Insider: “We always prioritize safety over speed records, but our highly trained pilots made the most of the conditions to get customers back to London well ahead of time.”
Storm Ciara was responsible for major travel disruptions across over the weekend, with 25,000 passengers affected by flight cancellations from Heathrow Airport alone, according to The Independent.
