KAL Limousine Bus — ₩17,000 direct to major hotels (60-90 min, comfortable). Taxi ₩70,000-₩90,000 (1-1.5h, traffic-dependent). The Magnetic Levitation train was discontinued in 2021.

Free shuttle bus T1↔T2 — every 5-10 minutes, 15-min ride. Allow 60-90 min total for an inter-terminal connection (15 min walk to bus + 15 min ride + 30-45 min check-in + security). Same-terminal connections: 60 min minimum domestic, 90 min international. Korean Air ↔ Asiana (T2 to T1) requires the shuttle — no airside connection.
