Seoul Incheon Airport Informational Guide to Seoul Incheon International Airport (ICN) - Non Official

Incheon Airport Train

Incheon Airport has three train options for all its passengers.

Our recommendation is to take the AREX train as it is the quickest option to Seoul and the cheapest one:


An Express Train to Seoul and a good option to get around. 

See more information in the Arex section


A high-speed magnetic levitation train and a quick way to get to Seoul city centre. 

See more information in Maglev section

Korea train express (ktx)

It is the national rail company and operates bullet train services from Incheon Airport.

Korea Train Express (KTX) is South Korea’s high-speed rail system that connects the country’s major cities, including Seoul, Busan and Mokpo, being a really good option if you need to travel to other South Korea cities.
