How WN4379 actually runs

Pro Flight Search has tracked every published board update for WN4379 across the BHM and HOU 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 (~28 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how WN4379 operates rather than what the timetable promises. Numbers refresh as new flights operate.
