What is the best way to get in and out of airports in London and Seoul?

London has six airports: London Heathrow (LHR), London Gatwick (LGW), London Stansted (STN), London Luton (LTN), London City (LCY), and London Southend (SEN). The larger airports of Heathrow and Gatwick are closer to central London and have better connectivity in terms of transport. Heathrow is the largest and best-connected of all the airports, with easy access from both the M4 and M25 (the London Orbital) motorways, which means if you have a hire car, then this is a good option. It is also well connected to the city centre on the London Underground system (Piccadilly Line) and the Heathrow Express. Gatwick, Stansted, Luton and Southend all have good road and rail connections (though they do not have subway/metro access to the London CBD). London City Airport is served by the Docklands Light Railway. Seoul has two major airports: Incheon (ICN) and Gimpo (GMP). Incheon is connected to both Gimpo Airport and central Seoul via the Airport Railroad Express (AREX). Which cities can you get to from Seoul Incheon (ICN)? Aside from Seoul, the adjacent city of Incheon is easily accessible from South Korea’s main international airport. The country’s second-largest city, Busan, located on the coast of the Korean peninsula, is easily accessible to travellers by plane from Incheon, as is Jeju, the holiday island off the coast of South Korea. Flights from Seoul to Jeju are very popular.

What are the benefits of the different airports in London and Seoul?

If you’re looking for cheap flights from London to Seoul, consider using one of London’s smaller airports, and avoid Heathrow, the British capital’s biggest airport and a central international hub. Low-cost flights out of London, connecting to other European hubs and then onto Seoul, are often cheaper from the second-tier airports of London Stansted and London Luton. If you need to leave London in a hurry, London City Airport is the closest to central London, followed by Heathrow. A short hop flight from London City Airport across the English Channel to the European mainland can connect you to a plethora of flight options onwards to Seoul. Seoul’s second (and older) airport is Gimpo, which only offers flights from London to Seoul via the Far East, most notably China and Japan, so you need to route yourself to Seoul via those countries. Gimpo is much closer to central Seoul than Incheon.

Which airlines fly direct from London to Seoul?

Only Korean Air offers non-stop London to Seoul flights, with direct service between London Heathrow Airport (LHR) and Seoul’s Incheon International Airport (ICN). Other options require at least one stop. When choosing flights from London to Seoul, alternatives to weigh up include via Hamad International Airport in Doha (DOH) on Qatar Airways or via Dubai International Airport (DXB) on Emirates. You can also take the same flights from London to Seoul via Doha (Qatar Airways) and Dubai (Emirates) from London Gatwick Airport (LGW). Otherwise, in your quest to find flights from London to Seoul, why not route yourself to the Korean capital via Amsterdam Schipol Airport on KLM Royal Dutch Airlines, via Frankfurt Airport (FRA) or Munich’s Franz Josef Strauss Airport (MUC) on Lufthansa, or via Paris Charles de Gaulle Airport (CDG) on Air France? Fancy a trip to Mother Russia on your flight from London to Seoul? How about on Aeroflot via Moscow’s Sheremetyevo Airport (SVO)? Flight times are around 11 hours if you’re flying non-stop direct flights from London to Seoul (LHR-ICN), or can range anywhere between 13 hours and 38 hours if you choose to fly from an airport other than London Heathrow.
