It also remains clear that this city pair has been reflected in individual airline statistics that the flight-tracking company has reported.

Take Korean Air (Pictured above), for example. You can see that both Seoul Airports and Jeju City are in the top three busiest airports for the carrier.

Jeju Air is a little bit different as they operate an equal amount of flights between Jeju City and Seoul Incheon, with again the other Seoul Airport coming third like the other carriers above.

Whilst Air Seoul operates fewer flights per day than its other competitors, the pattern of the busiest airports remains the same.

Finally, Jin Air, as to no surprise, also has both Seoul Airports and Jeju City in the top three for average daily movements, but Jeju City remains at the top.

Overall…


It remains clear that the Seoul-Jeju City pair remains the busiest air link in the world thus far, and no other route looks certain to top it or near it.

Looking ahead, especially with the rise in air travel post-COVID, competitors operating this route will no doubt continue to reap the rewards. They could always push up more frequencies moving forward.

For now, all eyes will be on the competitors to see how much lower airfares could become on this route if more flights will be added.
