The flight from New York's JFK to London Heathrow (LHR) is one of the busiest international routes in the world, with over a dozen daily non-stops between multiple carriers. Distance is roughly 5,540 km (3,440 miles), with a typical eastbound flight time of 7 hours and westbound flight time of 7.5 to 8 hours due to prevailing winds.
Who flies it
British Airways, American Airlines, Delta, Virgin Atlantic, JetBlue, and United all operate non-stops. Frequencies are highest with BA and AA (joint-venture partners), often with multiple daily departures in each direction. Premium-cabin product varies significantly between carriers — BA's Club Suite, Virgin's Upper Class, and JetBlue's Mint are all on this route.
Best time to fly
- Cheapest: Late January through early March, and the first half of November.
- Most expensive: Mid-June through August, and the last two weeks of December.
- Best weather window: May, September, and early October generally offer the best balance of price and weather on both ends.
Practical considerations
Heathrow is congested and connections off the JFK-LHR flight to onward European destinations should allow 90 minutes. JFK has multiple terminals depending on carrier — BA uses T7 (currently being phased out), AA uses T8, Delta uses T4, JetBlue uses T5, Virgin uses T4. Eastbound red-eyes are typically 6–7 hours; arrival times are early morning London time, which can mean a long first day. Westbound is a daytime flight.
