How WN3859 actually runs

Pro Flight Search has tracked every published board update for WN3859 across the STL and MCO boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left right on schedule but landed about 16 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3859 operates rather than what the timetable promises. Numbers refresh as new flights operate.
