How WN3981 actually runs

Pro Flight Search has tracked every published board update for WN3981 across the SMF and SNA boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left right on schedule but landed about 11 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3981 operates rather than what the timetable promises. Numbers refresh as new flights operate.
