How WN4851 actually runs

Pro Flight Search has tracked every published board update for WN4851 across the DAL and SLC boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left a little late (~17 min) but landed about 6 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN4851 operates rather than what the timetable promises. Numbers refresh as new flights operate.
