If you mean "just a few hours," the answer in 2026 is still no for standard commercial travel. Since the retirement of the Concorde in 2003, supersonic passenger flight has been absent from the skies. A typical non-stop flight from London Heathrow (LHR) to New York (JFK) currently takes approximately 7 to 8 hours eastbound and about 8 to 9 hours westbound due to prevailing jet stream winds. While companies like Boom Supersonic are actively testing aircraft (the Overture) designed to fly from London to New York in about 3.5 hours, these are not yet in commercial service in early 2026. For now, the "fastest" way to cross the Atlantic is by catching a flight during a particularly strong jet stream event, which can occasionally shave 45 to 60 minutes off the standard flight time, but "a few hours" remains a goal for the next decade of aviation technology.
