How UA425 actually runs

Pro Flight Search has tracked every published board update for UA425 across the ATL and IAH boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left a little late (~18 min) but landed about 23 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA425 operates rather than what the timetable promises. Numbers refresh as new flights operate.
