How WN909 actually runs

Pro Flight Search has tracked every published board update for WN909 across the BOS and BWI 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 9 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN909 operates rather than what the timetable promises. Numbers refresh as new flights operate.
