How WN4072 actually runs

Pro Flight Search has tracked every published board update for WN4072 across the STL and FLL boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left heavily delayed (~49 min) but landed noticeably late (~30 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how WN4072 operates rather than what the timetable promises. Numbers refresh as new flights operate.
