How UA4860 actually runs
Pro Flight Search has tracked every published board update for UA4860 across the ROC and IAD boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left a little late (~19 min) but landed about 11 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how UA4860 operates rather than what the timetable promises. Numbers refresh as new flights operate.
