I know there is a subway between Inchon airport and Seoul.
How long does it take to get Seoul from the airport by subway?
It depends on the terminal you arrive and also your destination. If you depart from terminal 1 to Seoul station, it takes about 1 hour. If it's terminal 2, it's about 1 hour and 10 minutes.It's just one station difference. If you want more information, leave a comment :)
Thank you so much. 고맙습니다. 선생님.
It is very kind and helpful answer. I hope to see you in Seoul soon.
