Best for different travel situations
Best for lower cost
Compare AREX and subway options, especially during daytime arrivals.
Best for late-night arrival
Check current train, bus, and taxi availability before arrival. Do not assume late-night service is available for every route.
Best for first-time visitors
Save your hotel address, phone number, and a map link before leaving the airport.
Step 1. Confirm your exact destination
Check whether your hotel or meeting point is near Busan, a nearby subway station, or a different district with a similar name.
Step 2. Compare luggage and transfer comfort
A cheaper route can become harder with large bags, stairs, or multiple transfers. Choose by time, luggage, and comfort, not only price.

Keep KRW or a usable card ready, and copy your hotel address in English and Korean if possible.
