About Korean Air flights from Seoul to Tokyo
Korean Air operates flights between Seoul and Tokyo, two of East Asia's major business and leisure hubs. Passengers can depart from either Gimpo International Airport (GMP) or Incheon International Airport (ICN) in Seoul and arrive at Haneda Airport (HND) or Narita International Airport (NRT) in Tokyo. The route covers 1,149 km and typically takes 155 minutes of flight time. Korean Air usually flies this route non-stop, making it a convenient option for both short business trips and longer stays.
Fares tend to be lowest in September, so booking in advance for that period may offer better prices. On economy fares, one checked bag weighing up to 23 kg is included in your baggage allowance. Online check-in opens 48 hours before departure and closes 60 minutes before takeoff, allowing you to complete this step from home or your mobile device.
