Seoul Station to Incheon Airport: AREX vs Bus
Compare AREX Express, the All-Stop Train and bus 6702 from Seoul Station to Incheon Airport: fares, journey times, T1/T2 access and how much time to allow.
Your KTX or subway arrival time is not your airport-bus boarding time. Compare the walk inside Seoul Station to AREX with access to the 6702 bus stop, then choose the correct T1/T2 service. For 6001, Seoul Station Exit 3 and Transfer Center Platform 3 are also different places.
