How UA2400 actually runs

Pro Flight Search has tracked every published board update for UA2400 across the BOS and LAS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left right on schedule but landed about 24 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA2400 operates rather than what the timetable promises. Numbers refresh as new flights operate.
