How WN4208 actually runs

Pro Flight Search has tracked every published board update for WN4208 across the BNA and BOS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~128 min) but landed heavily delayed (~113 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how WN4208 operates rather than what the timetable promises. Numbers refresh as new flights operate.
