How UA1976 actually runs

Pro Flight Search has tracked every published board update for UA1976 across the BOS and TUS 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 14 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA1976 operates rather than what the timetable promises. Numbers refresh as new flights operate.
