The Incheon International Airport Railroad (AREX) linking Seoul Station to Incheon International Airport will whisk travelers to their flights in 43 minutes, roughly 15 minutes shorter than via airport limousine. The fare is 13,300 won ($11.59) and makes no stops. The express train runs every 30 minutes, and operating hours are from 5:30 a.m. to 10 p.m.As I posted back in November, according to a Hankyoreh article I read, the transfers at Hongdae Station and Gongdeok wouldn't open until later. Obviously, I was confused when I saw this sign at Gimpo Airport Station.
A local train with 10 stops runs the same Incheon route in 53 minutes and only costs 3,700 won. The stops include Hongik University, Digital Media City, Gimpo Airport, Gyeyang, Geomam, Unseo and Incheon International Airport Cargo Terminal. (Gongdeok Station will open at the end of next year.) The hours of the commuter line are 5:20 a.m. to 12:00 a.m.
Travelers departing for Gimpo Airport can use the local line from Seoul Station. The trip takes 19 minutes and costs 1,200 won.
The Hongdae transfer was listed, and though I didn't get a chance to try it out yesterday, a friend of mine (who I sorely disappointed when I mentioned the Hongdae transfer wouldn't be open for some time) messaged me to tell me it was indeed open, and that the trip from Banghwa Station to Hongdae took 20 minutes. When I tell people I live near Gimpo Airport, I often hear about how 'far' away it is. It started getting closer with Line 9, and it's even closer now with this new line open. It'll be nice to finally take a ride on it, seeing as I've been photographing its construction for the last four years.
