Numerous flights disrupted at Jeju Airport due to extensive rainfall across the country
In a weather-related disruption, over 50 flights at Jeju International Airport were canceled or delayed on July 17, 2025, due to heavy rains affecting the central and southern regions of South Korea. The affected flights included 26 domestic departures, 25 domestic arrivals, and 2 international flights, with an additional 54 domestic departures and 56 domestic arrivals delayed [1].
The heavy downpours, which were not limited to Jeju Island, also impacted other regional airports, contributing to the flight cancellations and delays at Jeju International Airport [3]. As of 6:00 p.m. on the same day, 26 domestic departure flights had been canceled, and 25 domestic arrival flights were also canceled [2].
However, as of July 18 and 19, 2025, the flight operations at Jeju International Airport are currently functional, with flights resuming according to scheduled timetables. Airlines such as Jeju Air and T'way Air are operating their scheduled flights between Gimpo International Airport and Jeju, for instance [4][5].
Despite the improvement, travelers are advised to check real-time flight status due to possible lingering weather impacts. The heavy rains or typhoons in the country's central and southern parts may continue to cause flight disruptions [6].
Jeju International Airport, which serves as the gateway to southern Jeju Island, is not the only airport affected by the weather. Other regional airports are also experiencing flight disruptions due to the heavy rains [7]. The heavy rains in the country's central and southern parts are a common occurrence during the month of July [8].
