How accurate is this flight time calculator?

The time is usually within about 30 minutes of the real scheduled time, and the distance is exact because it comes straight from each airport's coordinates. Actual times move with the winds (the jet stream can add or cut 30 to 60 minutes on long routes), air traffic routing and the aircraft type.

Does the flight time include layovers?

No. The calculator shows the estimated time for a direct, nonstop flight. If your itinerary has a connection, add the layover time (typically 1 to 3 hours) plus the second flight's duration. For city pairs with no nonstop service, the real total travel time will be considerably longer than the number shown.

Why is a flight faster going east than west?

High altitude winds, mainly the jet stream, flow generally west to east, so eastbound flights ride a tailwind and arrive sooner while westbound flights fight a headwind. On a route like New York to London the gap can be 45 to 60 minutes. This calculator shows one direction neutral estimate, so treat it as the average of the two.

What is great circle distance?

It is the shortest distance between two points on the surface of a sphere, in this case the earth. Because the earth is curved, that path looks like a curve on a flat map, which is why long flights appear to arc toward the poles. Airlines fly close to great circle routes to save time and fuel.

How do I calculate my arrival time in another time zone?

Take your departure time, add the flight duration, then add the time zone difference between the two cities. Enter a departure time in the calculator above and it does both steps for you, and flags when you land the next day. New York to London leaving at 21:00 lands around 09:31 the following morning.

What counts as a short haul flight?

Short haul usually means under about 3 hours, which covers most flights inside Europe or between nearby US cities. Medium haul runs roughly 3 to 6 hours, and long haul is anything beyond that. Airlines draw the lines differently, and the cabin, meal service and baggage rules often change at those thresholds.

Does the calculator account for daylight saving time?

No. The time zone difference and the arrival time use standard UTC offsets, so they can be an hour out for either city during its daylight saving period. Double check around late March, late October and early November, when the two cities may not switch on the same date.

In Brief

How long is a flight, and how is flight time worked out?

Flight time is the great circle distance between two airports divided by a cruise speed of about 800 km/h (500 mph), plus roughly 36 minutes for taxi, takeoff, climb, descent and landing. New York to London is 3,442 miles and takes about 7 hours 30 minutes nonstop. This calculator uses real airport coordinates, so the distance is exact and the time lands within about 30 minutes for a direct flight.

How flight time and distance are calculated

Flight time comes from the great circle distance between the two airports, the shortest path across a curved earth, divided by a cruise speed of about 800 km/h, plus roughly 36 minutes for taxi, climb and descent. New York to London measures 3,442 miles, or 5,540 km.

Distance uses the haversine formula on each airport's latitude and longitude, so it is exact rather than rounded off a lookup table. The block speed rises from about 800 km/h on short and medium sectors toward 880 km/h on ultra long haul, where aircraft cruise higher and more efficiently. The model is calibrated against real scheduled block times on routes like JFK to Heathrow, Los Angeles to Haneda and Sydney to Los Angeles, and lands within about 20 minutes on those. Air miles quoted by frequent flyer schemes are usually this same great circle distance in statute miles.

Flight times from New York

Working out your arrival time in another time zone

Your arrival time is the departure time plus the flight duration plus the time zone difference. New York to London leaving at 21:00 lands about 09:31 the next morning, because London is five hours ahead. Enter a departure time in the tool above and it handles the date rollover for you.

Two things catch people out. The first is the day change: any eastbound flight leaving in the evening usually lands the following day, and a westbound Pacific crossing can land before it left in local terms. The second is daylight saving. The offsets here are standard ones, so around late March, late October and early November the two cities may not have switched on the same date and the arrival time can be an hour out.

Overnight flights and what they really cost you in sleep

An overnight flight leaves in the evening and lands the next morning. New York to London is the classic one at about 7h 31m, but only five or six of those hours are sleepable once the meal service and the descent are taken out. Eastbound crossings feel shortest and hurt most.

The useful number is not the flight time, it is the flight time minus about 90 minutes of service at each end. On anything under 8 hours eastbound, plan on arriving tired and book somewhere you can check in early rather than counting on a full night. Westbound overnights are rarer and easier, because you are effectively staying up later rather than losing a night.

Hotels with early check-in in LondonLand at 09:30, get into a room before noon

How much layover time you need

A layover needs at least 45 minutes on a domestic connection and 60 to 90 minutes internationally, and closer to 2 hours if you change terminals or clear immigration. The flight time on this page is nonstop only, so add the layover and the second sector to get your real door to door total.
