I'm at ICN now and see numerous planes parked at the new terminal but as far as I know it's still in the testing mode.

Asiana will move their checkin counters to K/L, which is on the complete opposite side of the terminal. The idea is to group the *A carrier's checkin counters together on the western side and Skyteam with KE on the eastern side. So anyone traveling soon to ICN should pay attention to the signs, rather than assuming the checkin counters are the same as your last trip, to avoid a lot of unnecessary walking from one side of the terminal to the other.

Asiana will open a new lounge on the western side but I'm not sure of the exact location. Asiana flights will generally depart from gates on the western side while KE will use gates on the eastern side. All other airlines, including *A carriers will use gates on the new Concourse A terminal. SQ will open a new lounge at the Concourse A terminal. SQ and OZ are currently the only *A carriers with lounges at ICN but not sure if any of the others will open a new lounge or not. I haven't heard of any plans. There is a train/tram located near the center of the terminal, after you pass through immigration, that will take you from the main concourse to the new Concourse A. There is no immigration or checkin at Concourse A.

SQ and OZ have some of the best lounges in the *A world so I'm looking forward to their new lounges and hopefully they're at least up to the standards of their old lounges.
