A private jet flight from the UK (typically London) to the USA (East Coast, like New York) generally takes between 7 and 8 hours, depending on the aircraft type and prevailing headwinds. While the physical speed of a private jet like a Gulfstream G650 or a Global 7500 is slightly higher than a commercial airliner, the real "time savings" come from the ground experience. Because private flyers can use smaller "FBO" terminals and avoid the long security and boarding queues of Heathrow, they can arrive just 15 minutes before departure. This "curb-to-cockpit" efficiency can save 3 to 4 hours of total travel time. For West Coast destinations like Los Angeles, a non-stop private flight will take about 10 to 11 hours. Note that smaller private jets may require a "tech stop" in Iceland or Newfoundland for refueling, which can add about 45 to 60 minutes to the total journey compared to an ultra-long-range jet that flies direct.
