How WN404 actually runs

Pro Flight Search has tracked every published board update for WN404 across the AUS and SJC boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left noticeably late (~28 min) but landed about 27 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN404 operates rather than what the timetable promises. Numbers refresh as new flights operate.
