How WN477 actually runs

Pro Flight Search has tracked every published board update for WN477 across the BOI and MDW boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left noticeably late (~25 min) but landed right on schedule. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN477 operates rather than what the timetable promises. Numbers refresh as new flights operate.
