How WN4371 actually runs

Pro Flight Search has tracked every published board update for WN4371 across the SMF and PHX boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left noticeably late (~35 min) but landed a little late (~20 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how WN4371 operates rather than what the timetable promises. Numbers refresh as new flights operate.
