After ticketing, Air Busan lets passengers purchase extra checked baggage online. Its official policy allows purchase or refund until two days before departure, based on Korean time. From the day before departure through departure day, cancellation and refund of prepaid baggage are not allowed. The purchased allowance belongs to the named passenger and cannot be transferred. It applies to checked baggage handed over at the airport counter rather than bags surrendered at the boarding gate. An updated price schedule applies from 8 September 2025, with charges varying by destination and increments such as 5 kg. Confirm the route, ticket rules and included allowance before paying.
