The Westside to London overnight
Los Angeles to London is 5,440 miles. The Gulfstream G650, Global 6000 and Falcon 8X fly it non-stop in about ten hours with the jet stream behind them. A heavy jet such as the Legacy 650 stops on the East Coast or in Canada and lands about two hours later.
The eight-hour time difference favours an overnight flight. Leave Van Nuys at 7 pm, sleep, and land at Farnborough at 1 pm the next day. Van Nuys restricts the loudest aircraft after 10 pm, so a very late departure may mean Burbank or LAX. VIP airliners depart from LAX.
London hosts many large-cabin aircraft, so a round trip with the aircraft waiting in England usually costs less than two one-way flights.
Which airport to leave from and which to land at are set out in our guides to the private jet airports in Los Angeles and the private jet airports in London: FBOs, customs and curfews, side by side.
