How WN3503 actually runs

Pro Flight Search has tracked every published board update for WN3503 across the SDF and PHX 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 25 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3503 operates rather than what the timetable promises. Numbers refresh as new flights operate.
