How WN1240 actually runs
Pro Flight Search has tracked every published board update for WN1240 across the CMH and BNA boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left heavily delayed (~126 min) but landed heavily delayed (~116 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how WN1240 operates rather than what the timetable promises. Numbers refresh as new flights operate.
