How UA978 actually runs

Pro Flight Search has tracked every published board update for UA978 across the IAD and EDI boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left right on schedule but landed about 20 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA978 operates rather than what the timetable promises. Numbers refresh as new flights operate.
