Air Busan advises passengers to contact its branch at the arrival airport for items left onboard an Air Busan flight. The airline may keep items found in the cabin for up to two weeks before donation or disposal; perishables can be disposed of sooner. Property found in airport arrival or departure areas may instead be handed directly to the airport lost-property office. The airline's domestic list includes Gimhae branch 051-974-8716, Gimpo branch 02-6226-1072 and Jeju branch 064-800-6545. International destinations use different branches and telephone numbers. Have your flight number, date, seat and an item description ready.
