Dinner in Manhattan, breakfast in London
New York to London is the most flown private route across the Atlantic. Eastbound is the shorter direction, with the jet stream behind you: a heavy jet crosses in about six hours forty-five. Ultra-long-range cabins are faster and quieter. A super-midsize jet refuels at Gander or Shannon and arrives about an hour later at a lower price.
The five-hour time difference makes the overnight the natural pattern. Leave Teterboro at 8 pm, sleep, and land at Farnborough at 8 am with the day ahead. Farnborough opens at 7 am and Biggin Hill at 6.30 am, so we time the departure to the airport; Luton and Stansted are open around the clock.
Teterboro caps aircraft at 100,000 lb, so VIP airliners leave from JFK or Newark; Westchester is the quieter departure for the Upper East Side and Connecticut.
