Jeju's official night-bus list identifies 3001 as a loop linking Jeju Airport, Nohyeong and Jungang-ro, operating weekdays and holidays. Route 3008 connects Tamra Library, Halla Hospital, the airport and Oedo on holidays. Many other 3000-series routes serve school-related travel, so the series number alone does not imply an airport service. Check actual late-night times, the last bus, stops and date-specific 2026 changes on the live Jeju bus system. Arrange an alternative if service is uncertain.
