Same journey, a different airport nearby - with an observed direct connection.
The distance between Incheon International Airport (ICN) and Nagasaki Airport (NGS) is approximately 370 mi; no direct connection has been observed in our route data.
The route data comes from the flight archive (ADS-B, adsb.lol): which connections actually flew over the last twelve full months and who flew them, combined with our own airport, runway, and airline datasets. It is reference data about observed routes - not a current timetable and no claim about bookability.
The flight archive of the last twelve months has nothing for this route, so we say nothing about frequency.
