The fine was issued after a group of international travelers arriving at Gimpo Airport were taken to the domestic terminal by mistake.
As a result of the confusion, four passengers walked out of the airport without undergoing mandatory immigration checks.
The incident happened on Korean Air flight KE2106, which had flown in from Tokyo on June 7, according to The Korea Herald.
After landing, passengers got on shuttle buses meant to take them to the international terminal, but one bus carrying 52 passengers accidentally drove to the domestic terminal instead.
