Storms grounded scores of planes at Jeju International Airport on Sunday, preventing around 30,000 passengers from boarding their flights. Weather officials said flights would resume on Monday.
Officials at the Korea Airports Corporation and carriers said a wind shear warning was issued at Jeju International Airport at 11 a.m. Saturday and a strong-wind warning at the same time on Sunday.
The first flight to be cancelled was an Asiana Airlines flight due at Jeju International Airport at 11:15 a.m. en route from Gimpo Airport on Sunday morning, followed by another 233, while another 58 were delayed and 21 flights sent back.
Korean Air, Asiana and Jeju Air cancelled all their flights to the southern resort island on Sunday. As a result, around 16,000 passengers were grounded on Jeju Island and another 14,000 could not get there on schedule.
Passengers lined up in droves in front of ticketing counters at Jeju International Airport late into the night to book flights the following day. Some protested strongly.
Airlines are considering adding extra flights on Monday to accommodate the stranded passengers.
Meanwhile, rain was forecast to continue until Monday morning accompanied by strong winds, according to the Korea Meteorological Administration. Weather officials predicted winds of more than 14 m/s on Jeju.
