Seoul Air Base (SSN) is a small joint military-civilian airfield in Seongnam, primarily used for government, military, and limited charter operations rather than scheduled international connections. Because it lacks the passenger volume and multi-terminal complexity of major hubs like Incheon or Gimpo, connections here are rare and typically involve simple, single-building transfers with minimal congestion. SSN has a single small terminal building, so all passenger movement is on foot with no trains, shuttles, or buses required between gates. Security re-screening is minimal and typically only applies when transferring between military and civilian-cleared areas of the facility.
