How WN3845 actually runs

Pro Flight Search has tracked every published board update for WN3845 across the STL and LAS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left a little late (~7 min) but landed right on schedule. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3845 operates rather than what the timetable promises. Numbers refresh as new flights operate.
