How long is the flight from Seoul to London?
A non-stop flight from Seoul to London takes about 11 hours and 15 minutes. The two cities are 8,861 km (5,506 miles) apart in a straight line, measured between Incheon (ICN) and Heathrow (LHR).
The estimate assumes an average speed of about 830 km/h plus around 35 minutes for taxiing, take-off and landing. Real schedules vary with the airline, aircraft, route and winds – heading west into the jet stream, flights often take a little longer than this. Check your booking for the exact time.
Time difference and arrival time
London is 9 hours behind Seoul right now. A flight leaving Seoul at 10:00 local time lands at about 12:15 local time in London. With a 9h shift, expect some jet lag: as a rough guide the body adjusts by about an hour a day, and flying west (as on this trip) is usually easier than the other way.

Why arrival times look strange
Airline schedules always show local times: departure in the departure city’s time and arrival in the arrival city’s time. Fly east and you “lose” hours – a 7-hour flight from New York to London leaving at 19:00 lands at 07:00 the next morning. Fly west and you gain them, which is how you can land in Los Angeles almost at the same clock time you left Tokyo. This calculator handles the time zones and daylight saving time for you.
How the flight time estimate works
In estimate mode the calculator measures the great-circle distance between the two cities – the shortest route over the Earth’s surface – and assumes an average speed of about 830 km/h (515 mph), plus around 35 minutes for taxiing, take-off and landing. That gives a good guide for a non-stop flight. Real schedules vary with the airline, aircraft, winds and route: flights heading east with the jet stream are often quicker than the same trip heading west, so always check your booking for the exact time.
