Fly from Incheon International Airport to London

London has played a part in the history of much of the world, and its many historic sites and iconic buildings draw millions of visitors every year. When you fly from Incheon International Airport (ICN) to London, expect the flight to last about 11 hours. Take the bus or subway system for fast access to ICN, and you can be having afternoon tea at Piccadilly Circus later that same day.


If this is your first visit to the city, spend a few days walking or riding the Tube through Central London, and then explore Convent Garden. From Piccadilly Circus, it's a short walk to the National Gallery. From there, continue on to Buckingham Palace and Westminster Abbey. Two notable landmarks somewhat farther away from this concentration are St. Paul s Cathedral and the Tower of London, both of which are immediately recognizable. An alternative view of London can be had from atop the London Eye, the world s largest observation wheel on the south bank of the Thames.

Hints and tips

When you fly from Incheon International Airport to London, your plane will touch down at Heathrow Airport (LHR). The airport is 17 miles west of Central London and is connected to the light rail system. Gatwick Airport (LGW) is a second airport that serves international travelers. While London is known for its fog, the sun comes out in the summer with average temperatures hitting the mid-70s. Guy Fawkes Day is celebrated on November 5th with bonfires and revelry.
