One airport at the Austin end, and its customs hours
Farnborough to Austin-Bergstrom is 4,255 nautical miles, 4,897 statute miles, a little further than London to Houston and about 475 nautical miles short of London to Los Angeles. The Falcon 7X is the smallest cabin we quote non-stop; the Gulfstream G650, Falcon 8X and Global 6000 fly it with more margin against the westbound winds.
Austin is six hours behind London. Leave Farnborough at 10 am and you land at Austin-Bergstrom around 2.30 pm local time, five miles from downtown and about fifteen minutes from South Congress or the Circuit of the Americas.
The hours at the Austin end shape the plan more than the flight itself. A customs officer meets private arrivals at the FBO, generally from 8.30 am to 9 pm, and permission to land is requested a business day ahead. A late London departure, or a weekend arrival booked after Friday, needs the times agreed before we confirm the aircraft.
Which London airport to leave from is set out in our guide to the private jet airports in London: FBOs, customs and curfews, side by side.
