How UA429 actually runs
Pro Flight Search has tracked every published board update for UA429 across the IAH and MEX boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~53 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how UA429 operates rather than what the timetable promises. Numbers refresh as new flights operate.
