Hi there,

My friend and I will be visiting Seoul in the near future. When we leave, he is travelling out on KE and I am departing on AA at around the same time, both from ICN. I have confirmed from the official ICN website that in fact Terminal 1 (and I concourse) AND Terminal 2 are all connected airside via underground train, and that the total time from Terminal 1 to Terminal 2 should be around 12-15 mins depending on length of transfer time at the I concourse. I also noticed that you go through a couple of "transfer gates" and a security check when making this transfer from 1 to 2 (or 2 to 1).

What I am wondering is this: Being the airport nerd that I am, if we arrive at ICN nice and early, and I check in for my AA flight in Terminal 1, is it possible for me to go visit Terminal 2 on the secure side so that we can just explore the new Terminal together for awhile before going our separate ways? Or would I require a boarding pass for a flight departing from Terminal 2 in order to make that transfer? Furthermore, would I actually need to clear security 3 times in order to do this (once after check-in at Terminal 1, again upon arriving by train at Terminal 2, and again upon returning by train to Terminal 1 or the I gates)? It's obviously not worth it if I have to clear security three times!

Any guidance here would be greatly appreciated as I'd love to explore the new terminal even though I don't happen to be flying KE/DL/AF/KL on this trip.

Thanks!

Daniel
