Heavy snowfall and strong winds forced a temporary halt to operations at Jeju International Airport on Sunday, leaving roughly 11,000 travelers unable to depart or arrive. Many passengers were stuck in terminals for hours as weather conditions made takeoffs and landings unsafe.
Runway use was suspended until late morning, with visibility and surface conditions deteriorating as snow continued to accumulate. Out of more than 460 planned flights, over a third were scrapped altogether, and several planes already en route had to be redirected to other airports. The resulting disruption created a significant backlog that is expected to take time to clear even after normal operations resume.
Airport teams worked continuously with snowplows and de-icing equipment to make the runways usable again, but the persistent storm limited how quickly flights could restart. Officials cautioned that passengers should expect delays and further schedule adjustments as airlines work through the congestion.
Weather agencies reported that Jeju’s higher elevations, particularly around the slopes of Mount Halla, saw more than 20 centimeters of snow within a day. This intense snowfall, combined with strong winds, sharply reduced visibility and contributed directly to the widespread cancellation and diversion of flights.
