A normal subsonic service took around 7-8 hours to fly from London to New York, but Concorde’s average flight time is around 3 hours 30 minutes, but can be slightly longer if the aircraft needs to hold before landing at the local airports. The fastest ever time for the crossing, the fastest ever set by a passenger aircraft, was 2 hours 52 minutes and 59 seconds. This was set by Captain Leslie Scott and his crew onboard G-BOAD, flying from New York to London, on the 7th of February 1996.
