How Long Fly From New York To London

1. New York to London Flight Time: The Short Answer

If you’re planning a trip across the pond, your first question is likely about travel time. For a direct, non-stop flight from New York City to London, the average flight time is approximately 7 hours.

However, the journey is not the same in both directions. The return flight from London back to New York is typically longer, averaging around 8 hours. This difference is due to a powerful, high-altitude wind that gives planes a helpful push on the way to Europe.

2. Direct Flights: Your Fastest Option

For the quickest journey, a direct (non-stop) flight is the only way to go.

Typical Time Range: While the average is 7 hours, you can expect most direct flights from NYC to London to fall within a range of 6 hours and 45 minutes to 7 hours and 30 minutes.
Major Airlines: This is one of a popular and competitive international routes. Major airlines offering direct flights include:
- British Airways
- American Airlines
- Virgin Atlantic
- Delta Air Lines
- JetBlue
- United Airlines
Common Airports: In New York, direct flights primarily depart from John F. Kennedy International Airport (JFK) and Newark Liberty International Airport (EWR). They typically arrive at London’s Heathrow Airport (LHR) or Gatwick Airport (LGW).

3. Why is the Flight Back to New York Longer? The Power of the Jet Stream

The reason for the time difference is a high-altitude, fast-flowing air current called the jet stream.

A Tailwind to London: The jet stream over the North Atlantic flows from west to east (from North America to Europe). When flying to London, commercial jets can enter this current and get a powerful “tailwind,” increasing their ground speed and shortening the flight.
A Headwind to New York: On the return journey, the plane is flying against this same current. This “headwind” slows the plane’s ground speed, forcing it to use more fuel and time to cover the same distance.

4. What About Flights with Layovers?

Choosing a flight with a layover can sometimes be cheaper, but it will always add significant time to your journey.

Flight Type	Average Flight Time	Total Travel Time	Common Layover Cities
Direct (Non-Stop)	~7 hours	7 – 8 hours	N/A
One-Stop	Varies	10 – 14+ hours	Reykjavik (KEF), Dublin (DUB), Amsterdam (AMS), Paris (CDG)

While you might save money, a one-stop flight can easily turn a 7-hour trip into an all-day or overnight ordeal.

5. Other Factors That Can Affect Flight Time

Aircraft Type: While the difference is minor on this route, different aircraft (like a Boeing 777 vs. an Airbus A350) have slightly different cruising speeds.
Specific Flight Path: Air traffic controllers may assign different routes to avoid weather or other air traffic, which can add or subtract a few minutes from the flight.
Seasonal Winds: The jet stream can be stronger and more variable in the winter, sometimes leading to even faster eastbound flights.

6. Planning Your Trip: Don’t Forget the Time Difference

It’s crucial to remember the significant time change when you land.

The 5-Hour Jump: London operates on Greenwich Mean Time (GMT) or British Summer Time (BST), while New York is on Eastern Time (ET). London is 5 hours ahead of New York.
Managing Jet Lag: Most flights to London are overnight. To help combat jet lag, follow this simple checklist:
- [✔] Hydrate: Drink plenty of water before and during the flight. Avoid excessive caffeine and alcohol.
- [✔] Sleep on the Plane: As soon as you’re at a comfortable cruising altitude, try to get as much sleep as possible. Use an eye mask and earplugs.
- [✔] Adopt the New Time Zone: When you land in the morning in London, try to stay awake until the evening. Exposing yourself to daylight will help your body clock adjust.
Helpful Link: You can use a tool like Time.is to check the current time difference.

7. Conclusion: So, How Long Should You Plan For?

When planning your trip from New York to London, it’s safe to budget around 7 to 7.5 hours for the eastbound journey and about 8 to 8.5 hours for the return flight if you are flying direct. Always check the specific flight details provided by your airline when booking, as this will give you the most accurate door-to-door schedule.

Takeaway

A direct flight from New York to London is your fastest option, taking about 7 hours. The return flight is longer, around 8 hours, due to the headwind from the jet stream. Remember to account for the 5-hour time difference when you land to help manage jet lag and plan your arrival activities.
