How WN645 actually runs

Pro Flight Search has tracked every published board update for WN645 across the BWI and PIT boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~33 min) but landed about 5 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN645 operates rather than what the timetable promises. Numbers refresh as new flights operate.
