Overview
JFK to London Heathrow — the most-flown long-haul corridor in the world, eastbound. Short, overnight, and the jet lag is real but compressible if you sleep on the plane.
Jet lag
5-hour eastward shift on a short overnight — the standard transatlantic challenge. Sleep as much as possible aligned to London night, get morning light on arrival, function the same day.
Build a JFK→LHR adaptation scheduleBest window side
Eastbound overnight — the right side faces north and gets the earliest sunrise approaching Europe. For sleep, choose the window and ignore the view.
Cabin humidity
A350-1000 or A330neo is meaningfully more humid than 777-300ER on a 7-hour overnight where sleep quality is most of the win.
