The Jeju International Airport prayer room (musalla) is a permanent ~30-square-metre prayer space inside the international departures concourse on Floor 2, accessible only after security and immigration. From Floor 3 (international check-in), pass through security and immigration, then take the escalator down one level to Floor 2; the prayer room is at the end of the hallway opposite Gate 22, near the duty-free area. Open daily 06:00–23:00. The main prayer space is shared, with two smaller separate rooms — one for men, one for women — and a wash tap and bidet for ablution (wudu). Prayer mats and qibla direction are provided. Note: this prayer room is post-immigration and not accessible from the domestic terminal or to non-flying visitors. For pre-flight prayers from the domestic concourse, the closest alternatives are Jeju Central Masjid (a 10-minute drive) and Wardah Restaurant's small in-house prayer room in Samdo-dong.
