Whilst in London, you can fly into busy airports such as London Heathrow Airport, Gatwick Airport, London City Airport, Stansted Airport and Luton Airport some of which are located outside the main metropolitan area but have good transport links to the city centre.

  • Which airlines fly directly from Korea to London?

    If you’re looking for the best deals to fly directly to London from Korea then you may find that there aren’t many airlines that operate direct services, there are some available, but they can be considerably more expensive than a flight with a stopover. Korean Air and Asiana Airlines both operate non-stop flights from Incheon International Airport to London Heathrow Airport, the flight duration for these flights ranges between 12h 05min and 12h 30min. Other notable airlines that provide flights with a stopover are Lufthansa, Finnair, Qatar Airways, LOT Polish Airlines, Turkish Airlines, Singapore Airlines, KLM and Etihad Airways.

  • What are the stopover options between Korea to London?

    When it comes to booking flights to London from Korea that includes a stopover or two, then you have plenty of options at your disposal. Lufthansa and Finnair both operate indirect flights from Incheon International Airport to London Heathrow with a reasonable flight time of around 14h 45min with a stopover in Frankfurt Am Main Airport (FRA) or Helsinki-Vantaa Airport (HEL) of 1h 30min or 2h 5min, respectively. Alternatively, if a lower price is more important to you, then check out flights with Qatar Airways via Doha Airport (DOH), Turkish Airlines via Istanbul Airport (IST) or Etihad Airways via Abu Dhabi Airport (AUH), all of which operate out of Incheon International Airport to London Heathrow with stopovers being relatively short between 2h-3h. From Jeju International Airport (CJU) you can fly to London Heathrow with Korean Air via Seoul Gimpo Airport. If you want to land at Gatwick Airport you can fly with Turkish Airlines from Incheon International Airport via Istanbul Airport, while KLM also provide a service via Amsterdam Schiphol Airport (AMS) to London City Airport (LCY). The cheaper flights tend to extend the flight duration by only around 5h-7h depending on who you fly with, and flights with two stopovers extend the flight time considerably without being any cheaper, so it’s best to go with one stopover if possible.
