AREX Master Guide
The fastest and smartest way to kickstart your Seoul adventure.
Welcome to South Korea! Once you clear customs at Incheon International Airport (ICN), your very first mission is getting to downtown Seoul.
The absolute best, most traffic-free option is the AREX (Airport Railroad Express). However, many first-time travelers get confused between the Express Train and the All-Stop Train. As a Seoul local, let me break down exactly which one you should choose for your 2026 trip.
CRITICAL NOTICE
Official Timetable Recheck Required
Train schedules, fares, and boarding platforms can change unexpectedly. It is absolutely mandatory to cross-check the live timetables on the Official Let’s Korail or the Airport Railroad official website before arriving.
📊 Quick Comparison: Express vs. All-Stop
1. The Premium Choice: AREX Express Train
If your final destination is near Seoul Station, Myeongdong, or Dongdaemun, this is your best bet. It goes straight to Seoul Station without a single stop. You get designated, comfortable seats, free Wi-Fi, and dedicated luggage racks.
Pro Tip: If you fly with Korean Air, Asiana Airlines, or Jeju Air, you can even use the City Airport Terminal at Seoul Station to check your bags and clear immigration early on your way back!
2. The Budget & Flexible Choice: All-Stop Train
Are you staying in Hongdae (Hongik Univ. Station) or Digital Media City? Do not take the Express train! The Express train does not stop at Hongdae. The All-Stop train functions like a regular commuter subway but has plenty of space for luggage if you board at the airport.

Jongsoo’s Local Insight
“Many bloggers tell you to always book the Express Train online to save money. But here is the real local secret: Check the next departure time first when you arrive!
The Express Train runs every 40 minutes, while the All-Stop runs every 10 minutes. If you just missed an Express Train, taking the All-Stop Train right away will actually get you to Seoul Station faster!”
Which One Should You Choose?
- Choose Express if: You want a comfortable, stress-free ride directly to Seoul Station with heavy luggage.
- Choose All-Stop if: Your hotel is in Hongdae, or you want to save money and don’t mind standing if it gets crowded.
