How WN2866 actually runs

Pro Flight Search has tracked every published board update for WN2866 across the MIA and MDW boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left heavily delayed (~68 min) but landed right on schedule. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN2866 operates rather than what the timetable promises. Numbers refresh as new flights operate.
