Air Busan operates an Unaccompanied Minor (UM) service for children travelling without a guardian. Its policy lists ages 5–12 for domestic flights and ages 5–11 for international flights; children under five cannot travel alone. The age at which a companion counts as an eligible guardian also differs between domestic and international services. Arrange the service with the booking center on 1666-3060 by the day before travel, and provide the details of adults handing over and collecting the child. UM applications and guardian undertakings must be completed at the airport. A service charge applies per flight sector and there are restrictions on promotional fares and certain countries. Check the entry rules for minors in destinations such as the Philippines or Vietnam separately.
