How much does a flight from New York to London cost?
How this was estimated. A base fare that rises with distance, adjusted for the typical price level of the countries involved and your cabin (economy). The low end is a cheap day booked one to three months ahead; the high end is a last-minute or peak-season ticket. A return ticket is usually about 1.76× the one-way fare, not double.
Not included: checked bags (on major US airlines commonly US$35 to US$45 for the first bag each way), seat selection, meals, and transport to the airport. Fares quoted here include typical taxes and airline fees.

How long is the flight from New York to London?
John F. Kennedy International Airport (JFK) in New York, United States is about 3,442 miles (5,540 km) from London Heathrow Airport (LHR) in London, England, United Kingdom. A non-stop wide-body jet flight takes about 6 hours 43 minutes gate to gate, with roughly 6 hours 18 minutes of that in the air. The jet stream gives this direction an average tailwind of about 54 mph, which shortens the trip compared with flying the other way. Timetables, weather and routing can move that by 10 percent either way, so the likely range is 6h 15m to 7h 23m.
There are no direct flights on every route, and a connection adds the layover plus a second take-off and landing. As a rule of thumb, add 1.5 to 3 hours for each stop, plus the risk of a missed connection on separate tickets.
How this flight time calculator works
It does three things for any pair of airports. First it finds the great-circle distance, the shortest line over the globe, using the haversine formula and each airport's exact coordinates. Second it estimates gate-to-gate time as a fixed allowance for taxiing, climb and descent plus distance divided by an average speed for the aircraft, corrected for the jet stream:
The jet-stream term uses the route's latitude and compass direction: strongest in the mid-latitudes (roughly 30° to 60°), close to zero near the equator, and always helping eastbound flights and slowing westbound ones. It applies only to the cruise part of the trip, so short hops are barely affected. Third, it estimates the ticket price from distance, the typical price level of the countries involved and the cabin, and shows the time difference between the two airports using the IANA time-zone database (including today's daylight saving rules).
| Aircraft class | Examples | Average speed | Overhead |
|---|---|---|---|
| Narrow-body jet | Boeing 737, Airbus A320 | 510 mph (821 km/h) | 50 min |
| Wide-body jet | Boeing 777 / 787, Airbus A330 / A350 | 540 mph (869 km/h) | 55 min |
| Regional jet | Embraer E175, Bombardier CRJ | 440 mph (708 km/h) | 45 min |
| Turboprop | ATR 72, De Havilland Dash 8 | 300 mph (483 km/h) | 35 min |
| Private jet | Citation, Challenger, Gulfstream | 520 mph (837 km/h) | 30 min |
We tuned these numbers against about 35 well-known scheduled routes (for example New York–Los Angeles, New York–London, Los Angeles–Tokyo, Delhi–Mumbai and Sydney–Singapore), where the model averaged within roughly 3 to 4 percent of published timetables. Real timetables include airline padding for congestion, so a specific flight may be listed longer or shorter. Airport data comes from the OurAirports project (public domain) through the airportsdata package.
Flight time, block time and door-to-door time
Time in the air
Wheels up to wheels down. This is what pilots log as flight time and is the shortest of the three figures.
Gate to gate (block time)
Pushback to arrival at the gate, including taxi and queues. This is the duration an airline timetable and your ticket show, and our headline result.
Door to door
Adds time at the airport before departure, immigration and baggage on arrival, and the journey to and from the airports. Often 4 to 6 hours more on an international trip.
What makes flights cost more or less
The US Bureau of Transportation Statistics put the average domestic ticket at $445 in the second quarter of 2026: about $312 for one-way tickets and $549 for round trips, counting taxes and required fees but not bag or seat fees (BTS release). That average hides a huge spread, which is why this calculator shows a range. These are the main levers, roughly in order of impact:
- •Distance and route. Longer flights cost more in total but less per mile. Routes dominated by one airline, or into small airports, cost more than busy competitive ones.
- •Booking window. Fares tend to be lowest roughly one to three months out and rise in the final two weeks. The estimate above adds a premium for dates under three weeks away.
- •Season and day. Summer, late December and school holidays are most expensive; January, February, September and October are usually cheaper. Tuesday, Wednesday and Saturday departures often beat Friday and Sunday.
- •Cabin. Premium economy is typically 1.3 to 1.8 times economy, business 2 to 4 times and first class up to 6 times on long-haul routes.
- •Fare type and extras. Basic economy fares usually exclude a free checked bag and seat choice. Compare the total after extras, not just the headline price.
- •Taxes and fees. US domestic tickets include a 7.5 percent federal excise tax and airport charges; international tickets add departure and arrival taxes that can be a significant share of a cheap fare.
Time zones, arrival time and jet lag
To work out the local time when you land, take your departure time, add the flight time, then add the time difference shown above (or subtract it if the destination is behind). Flying east you lose hours on the clock, so a 7-hour flight can land the next morning; flying west you gain them, and it is even possible to land “before” you left. Clocks change for daylight saving on different dates in different countries, so check the difference again if you travel in March, April, October or November.
Many travelers find it takes about a day to adjust for each one to two time zones crossed, and eastward trips are usually harder than westward ones. Morning daylight at the destination, staying hydrated and shifting your sleep an hour or two before you leave can help. This is general guidance, not medical advice.

Frequently asked questions
We first measure the great-circle distance between the two airports (the shortest path over the Earth's surface). Gate-to-gate time is then a fixed allowance for taxiing, climb and descent (about 45 to 55 minutes for an airliner) plus the distance divided by the average cruise speed, adjusted for the jet stream. A narrow-body jet averages roughly 510 mph and a wide-body about 540 mph over the whole trip.
The jet stream blows from west to east at cruising altitude, often at 50 to 150 mph. Eastbound flights ride that tailwind and westbound flights fight it. New York to London is typically around 6 hours 45 minutes, while London to New York is about 8 hours, even though the distance is the same.
Flight time is the time in the air, from wheels up to wheels down. Block time is what the airline timetable shows: from leaving the gate to arriving at the gate, so it also includes taxiing and queues. Block time is usually 20 to 30 minutes longer than the time in the air.
The distance is exact. The time is an estimate that we checked against about 35 well-known scheduled routes, where it averaged roughly 3 to 4 percent away from the timetable. Any single flight can differ by 10 percent or more because of the actual flight path, weather, air traffic control and the aircraft used, so treat the result as a planning figure and check your airline's timetable before you book.
It depends mostly on distance, season and how early you book. The US Bureau of Transportation Statistics reported an average domestic itinerary fare of $445 in the second quarter of 2026, made up of about $312 for one-way tickets and $549 for round trips, including taxes and required fees but not bag or seat fees. The calculator shows a low, typical and high range for your route, which is wider than a single average because the same seat can sell for very different prices.
Our estimate for a one-way economy ticket between New York (JFK) and London (LHR) is about $260 on a cheap day booked early, around $420 typically, and $800 or more last minute or in peak season. A return ticket is usually about 1.75 times the one-way price. The flight takes about 6 hours 45 minutes eastbound and about 8 hours back to New York.
Delhi (DEL) to London Heathrow (LHR) is about 4,180 miles (6,730 km). The non-stop flight takes roughly 9 hours 30 minutes, and about 8 hours in the other direction thanks to the jet stream. A one-way economy ticket typically costs around $465 (about ₹44,000), with cheap fares near $290 and last-minute fares near $890.
Delhi (DEL) to Mumbai (BOM) is about 707 miles (1,140 km) and takes roughly 2 hours 15 minutes gate to gate. A one-way economy ticket typically costs around ₹6,600 (about $70), from roughly ₹4,000 on a cheap day booked early to ₹12,000 or more at the last minute.
For most routes, booking roughly one to three months before departure tends to give the lowest fares, and prices usually climb in the last two weeks. Flying midweek (Tuesday or Wednesday) or on Saturday is often cheaper than Friday or Sunday, and travel outside school holidays, summer and late December is cheaper. These are patterns, not guarantees; the low end of our estimate reflects a cheap day booked early.
Allow the "Use my location" button and the calculator lists the closest major airports to your device. Without it, the starting airport is guessed from the approximate location of your internet connection, which can be a different city from yours, so always check it. You can also type your city, an airport name or its three-letter code to see every airport that serves it.
Yes. It shows how many hours the destination is ahead of or behind the departure airport today, using each airport's own time zone and current daylight saving rules. For your local arrival time, add the flight time to your departure time and then add or subtract that difference.
Many airlines and airports suggest arriving about two hours before a domestic flight and about three hours before an international one. Allow more at very large airports, during holiday periods, or if you are checking bags. Add that, plus the trip to the airport and time to leave the arrival airport, to the flight time for a realistic door-to-door estimate.
The longest scheduled non-stop services connect Singapore and New York, about 9,500 miles (15,300 km) and roughly 18 to 19 hours in the air. Other ultra-long routes include Perth to London and Auckland to Doha, each over 17 hours.
Yes. Choose "Private jet" as the aircraft. Private jets have less taxi and queuing time, so the gate-to-gate figure is shorter, and the cost section switches from a per-seat fare to an estimated charter price for the whole aircraft based on flight hours.
No. The routes you pick are not saved on our servers. The approximate location from your connection is used only in your browser to suggest an airport, and the precise location from the "Use my location" button never leaves your device.
Good to know: this calculator provides estimates for planning only. It does not use live flight schedules, weather or air traffic data, and it is not a booking service. Always confirm times and prices with your airline or travel agent. Your approximate location (from your internet connection) is used in your browser to suggest a starting airport and is not stored; the device-location button works only when you press it.
