I noticed definitely there is a priority security check entry at ICN near check-in counter L or M for Asiana. During I was stuck in the long slow queue, some of VIP-looking persons went through the X-ray. Surprising thing is that they, including the guards did not take off metals and ignore alarms
Before I enter, I noticed some conditions to use that gate but could not understand fully...
Hope this to be like NRT Star Gold priority security apart from general.
