How WN4004 actually runs
Pro Flight Search has tracked every published board update for WN4004 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 a little late (~8 min) but landed about 22 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how WN4004 operates rather than what the timetable promises. Numbers refresh as new flights operate.
