So, how long is the flight from New York to London? About 7 hours nonstop heading east, and closer to 8 hours flying back west. Airlines typically schedule New York JFK or Newark to London Heathrow at 6 hours 45 minutes to 7 hours 30 minutes, because the jet stream pushes eastbound planes across the Atlantic faster.
It’s one of the busiest long-haul routes on Earth, but the number on your ticket isn’t the whole story — direction, airport, and season all move the real flight time around.
Key Takeaways
- Eastbound, airlines schedule about 6 hours 45 minutes to 7 hours 30 minutes; westbound, 7 hours 45 minutes to 8 hours 15 minutes.
- Actual airborne time is shorter than the ticket time — Flightradar24 puts BA112’s typical time in the air at 6 hours 13 minutes.
- The fastest subsonic crossing ever on this route was BA112 in February 2020 — 4 hours 56 minutes, riding Storm Ciara’s jet stream.
- London is 5 hours ahead of New York most of the year, and briefly just 4 hours ahead during the clock-change gaps in March and October.
- Nonstops from JFK and Newark serve Heathrow and Gatwick on seven-plus airlines — compare prices.
How Long Is the Flight From New York to London, by Direction?
The route covers roughly 3,450 miles (about 5,550 km). The time on your ticket is “block time” — gate to gate, including taxiing at both ends — which is why it runs longer than your actual time in the air.
| Direction | Scheduled (Block) Time | Typical Airborne Time | Why |
|---|---|---|---|
| New York → London (eastbound) | 6h 45m – 7h 30m | About 6h – 6h 45m | Jet stream tailwind |
| London → New York (westbound) | 7h 45m – 8h 15m | About 7h 15m – 7h 45m | Flying against the jet stream |
How Long Is the Flight From New York to London — and Why the Return Takes Longer
Blame — or thank — the jet stream, a river of fast air that flows west to east across the Atlantic. Eastbound, your plane rides it like a moving walkway, and ground speeds can jump by 100 mph or more. Westbound, pilots fly against those same winds, and in winter they sometimes route north over Greenland just to dodge the worst of it. That’s why the gap between directions can stretch to nearly an hour in January and shrink in summer.
Every so often, the jet stream puts on a show: in February 2020, British Airways flight BA112 rode Storm Ciara’s winds from JFK to Heathrow in 4 hours 56 minutes — the fastest subsonic crossing ever recorded between the two cities, according to Flightradar24’s account of the record flight. Don’t plan around a repeat, but landing 30 minutes early on a windy winter night is perfectly normal.
Which Airports Will You Use?
London flights leave New York from JFK International Airport in Queens or Newark Liberty International Airport (EWR) in New Jersey. In London, most land at Heathrow (LHR), the main long-haul hub, with a solid selection into Gatwick (LGW) — a smart pick if you’re staying south of the Thames. All four airports have direct trains into the center, so let price and schedule decide. You can compare today’s live departures on FlightAware’s JFK to Heathrow flight finder.
Airlines That Fly New York to London Nonstop
- British Airways — most daily frequencies on the route, into Heathrow
- Virgin Atlantic — known for service and its Upper Class cabin

- JetBlue — serves both Heathrow and Gatwick
- Norse Atlantic Airways — the budget option into Gatwick
With that much competition, fares swing widely by date and time, so compare across airlines — and across JFK and Newark — first. The same timing logic applies to fares: traveling when everyone else isn’t is how you save, a pattern we break down in our guide to when to book an Antarctica cruise if you actually want to save money. And check your documents early — our explainer on how long it takes to get a passport covers current processing times, because a passport stuck in renewal ends more trips than bad weather does.
The Time Difference: London Is 5 Hours Ahead
London runs 5 hours ahead of New York for most of the year. (For a few weeks each March and October, when the US and UK change their clocks on different weekends, the gap briefly narrows to 4 hours.) A 7:00 p.m. departure from JFK lands at Heathrow around 7:00 a.m. the next morning — you lose most of the night in the air. Most eastbound flights are red-eyes, though a few morning departures land in the evening, and some travelers swear they’re gentler on the body clock.
Tips for the Overnight Flight to London
- Eat before you board. Dinner at the airport, then treat the flight as sleep time, not entertainment time.
- Set your watch to London time when you sit down — your brain starts adjusting early.
- Protect your sleep. Four or five hours of sleep beats any movie marathon. Eye mask, neck pillow, noise-canceling headphones.
- Hydrate steadily and go easy on alcohol and caffeine, both of which make jet lag meaner.
- Move around. A walk down the aisle or some stretches every couple of hours keeps your circulation honest.
Beating Jet Lag Once You Arrive
Get outside into daylight fast, and don’t surrender to a three-hour nap — twenty or thirty minutes is fine, but more leaves you wide awake at 3 a.m. Eat on London time, take a walk, and push through to a normal local bedtime; by day two, most people feel surprisingly human. The flight home is kinder: you gain five hours, so just stay up until your regular bedtime. Planning the wider trip too?

Frequently Asked Questions
How long is the flight from New York to London nonstop?
Nonstop flights are scheduled at about 6 hours 45 minutes to 7 hours 30 minutes eastbound, and around 8 hours westbound. Actual airborne time is a bit less, because the ticket includes taxiing at both airports.
Why is the return flight from London to New York longer?
The jet stream flows from west to east, so eastbound planes ride a powerful tailwind while westbound planes fly against it. The headwind adds roughly 45 to 60 minutes, and the gap grows in winter when the jet stream is strongest.
Which is better for London flights, JFK or Newark?
Both are good, and flight time is nearly identical. JFK offers the most choices; Newark can be quicker from Manhattan’s west side and New Jersey. Compare price and schedule.
What is the time difference between New York and London?
London is 5 hours ahead of New York for most of the year. The gap briefly drops to 4 hours during the spring and autumn weeks when the two countries change their clocks on different dates.
