Getting between terminals

The free inter-terminal shuttle at Incheon runs landside from the departures level, so using it means being screened again. There is an airside shuttle train from Terminal 1 to Terminal 2, but it exists for connecting passengers, runs one way only, and cannot be ridden back — it is not a way to visit a lounge in the other terminal and return to your gate. Passengers on separate tickets have no airside option at all.
