Leave London mid-morning, land in Houston mid-afternoon
Farnborough to Hobby is 4,198 nautical miles, 4,830 statute miles, about 350 nautical miles further than London to Miami. That extra distance decides the cabin. Most heavy jets need a fuel stop on the way to Miami; on this pair the Falcon 7X is the smallest cabin we quote non-stop, and the Gulfstream G650, Falcon 8X and Global 6000 fly it with more margin against the westbound winds.
Houston is six hours behind London. A 10 am departure from Farnborough lands at Hobby around 2 pm local time, with customs at the private terminal and downtown, the Texas Medical Center or the Energy Corridor still ahead of you that afternoon.
Much of the private traffic on this pair is energy business. CERAWeek in March and the Offshore Technology Conference in early May bring delegations from London, and on those weeks the Hobby ramp fills first, so we hold the parking with the booking.
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.
