Incheon Airport to Seoul: AREX express vs all-stop train

From the airport

• AREX runs from Incheon Airport to Seoul Station. The Express train is non-stop and reserved; the all-stop train is cheaper and takes T-money.
• Airport limousine buses go to most neighborhoods and hotels, and are easier with big luggage.
• Taxis are metered. Use official taxi stands and avoid drivers who approach you inside the terminal.
