❓ Frequently Asked Questions
AREX Express vs All-Stop vs Limousine Bus — which should I take?
The AREX Express (13,000 KRW, 43 min) is best for speed and comfort — reserved seating goes directly to Seoul Station. The AREX All-Stop (4,350 KRW, 51 min) is the budget choice and stops at Hongik University and other city-centre stations. The Limousine Bus Route 6001 (17,000 KRW, 60–90 min to City Hall) suits travellers with heavy luggage or heading to areas without nearby metro stations.
Which lounge can I access at ICN?
In T1: the Asiana Business Lounge is open to Asiana Business/First class passengers and Star Alliance Gold members (24h); the Matina Lounge accepts Priority Pass and business class (05:00–20:00).

Plaza Premium in both terminals is open to all passengers for a fee, 24 hours a day.
How early should I arrive for my flight?
For international flights, allow at least 3 hours before departure. For domestic flights, 2 hours is generally sufficient. If you are departing from T2 during peak periods (summer holidays, Lunar New Year, Chuseok), factor in extra time for the terminal transfer and immigration queues, especially when using automated kiosks for the first time.

Yes — free WiFi is available throughout T1 and T2. To connect, register at any self-service kiosk using either your passport or mobile phone number. The connection is fast and unlimited, covering departure halls, transit areas and lounges.
Where can I store luggage at ICN?
Luggage storage is available on the 1st floor of both T1 and T2. Prices start from 5,000 KRW per day for small bags and 8,000 KRW per day for large bags. This is ideal if you plan to take the free transit tour or explore Seoul during a long layover before returning to catch your flight.
