Route · KIX → GMP
Flights from Osaka to Seoul
The 834-kilometre hop between Osaka Kansai (KIX) and Seoul Gimpo (GMP) clocks in at roughly an hour and a half of block time, making it one of the most convenient international city-pairs in Northeast Asia and a genuine alternative to the longer Incheon routing for travellers who want to land close to central Seoul. Jeju Air and Asiana serve it frequently, with Korean Air and ANA rounding out the schedule on widebody and narrowbody equipment ranging from the A320 family to the 737-800. A practical note worth knowing: Gimpo's international terminal is compact and clears Korean immigration relatively quickly, and the airport rail link deposits you at Hongik University station in under thirty minutes. Fares tend to soften in the shoulder months of late January and mid-June, while weekend departures in either direction often carry a premium due to high leisure and VFR demand between Osaka's large Korean diaspora community and Seoul.
