Air Busan's official connection guide tells passengers connecting between its domestic and international flights at Gimhae to collect their bags and check in again. Connections between Air Busan and other airlines generally also require baggage collection and a fresh check-in at the connecting airport. A limited exception may apply to partner international connections at Incheon or Gimpo when an interline baggage arrangement exists; this must be confirmed in advance. International-to-international connections at Gimhae may depend on immigration, quarantine and visa conditions. Leave enough time for baggage reclaim, terminal transfers and formalities.
