Does ICN have a priority security queue/checkpoint for business class? I did a bunch of searching on the internet and I only find trip reports of being escorted to security for first class passengers, or for folks going through transit security.

We had a rather unpleasant experience in the normal (disorderly) security queue today(10 Feb). Could not locate a priority lane or checkpoint. If true, seems a rather unpleasant aspect of an otherwise quite cool airport.
