How WN1159 actually runs

Pro Flight Search has tracked every published board update for WN1159 across the BWI and MDW boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left noticeably late (~33 min) but landed a little late (~14 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how WN1159 operates rather than what the timetable promises. Numbers refresh as new flights operate.
