How YP3731 actually runs
Pro Flight Search has tracked every published board update for YP3731 across the ICN and NRT boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~22 min) but landed a little late (~11 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how YP3731 operates rather than what the timetable promises. Numbers refresh as new flights operate.
