TRAVEL
There are two international airports in Seoul. Most of you will come through ICN.
  1. Incheon International Airport (ICN)
    There are two recommended ways (airport limousine bus, subway) to come to Yonsei from ICN. The best way will be the airport limousine bus.
  2. Gimpo International Airport (GMP)
    There is only one recommended way (subway) to come to Yonsei from GMP.
The subway option always starts with the airport express train (AREX) (sometimes it's called Airport Railroad Express), which is a part of the whole subway system of Seoul, from each airport. Therefore you only need one ticket to come to Sinchon subway station (240).

Taxi (from both airports) is always a feasible solution.
For detailed info on how to come to Yonsei University from the airports, please read this guide page (PDF).
