How WN3851 actually runs

Pro Flight Search has tracked every published board update for WN3851 across the SNA and PHX boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left heavily delayed (~61 min) but landed about 14 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3851 operates rather than what the timetable promises. Numbers refresh as new flights operate.
