London to the Westside in one leg
London to Los Angeles is 5,440 miles, which the Gulfstream G650, Global 6000 and Falcon 8X fly non-stop in about eleven hours. A heavy jet such as the Legacy 650 stops on the East Coast or in Canada and lands about two hours later, which some clients prefer as a chance to stretch.
The eight-hour time difference is the route's gift: an 11 am departure from Farnborough lands at Van Nuys at 2 pm local time. Customs clears at the FBO by prior arrangement, and Beverly Hills is thirty minutes away. LAX takes the VIP airliners and has full customs; Burbank suits the studios and the hills.
Los Angeles is a base for a great many large-cabin aircraft, so the return leg prices well, and a round trip with the aircraft waiting in California is often the better value.
