💡 Choosing between AREX Express and All-Stop trains
AREX Express connects Seoul Station with Incheon Airport Terminal 1 in 43 minutes and Terminal 2 in 51 minutes. The published adult fare is ₩13,000 from either terminal and includes a reserved seat. This calculator multiplies that fare by the number of adults; it does not apply an automatic group discount.
All-Stop adult fares using a prepaid or postpaid transit card are ₩4,750 between Seoul Station and T1, or ₩5,350 between Seoul Station and T2. Typical journey times are 59 and 66 minutes respectively; some trains take another 2–6 minutes. Seats are unreserved. Select the correct terminal above; the result already includes the T2 fare when selected.
For an adult All-Stop single-use ticket, add ₩100 per person to the card fare. A separate ₩500 deposit per ticket is payable initially and refundable at the destination. Neither surcharge nor deposit is included in the transit-card estimate. No Express voucher is needed for All-Stop travel.
For intermediate destinations such as Hongik University or Gimpo Airport, use the All-Stop service and check the fare to that station. This calculator covers only journeys between Seoul Station and Incheon Airport, in either direction.
