How UA434 actually runs

Pro Flight Search has tracked every published board update for UA434 across the IAH and LAX boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left about 6 min early but landed about 16 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA434 operates rather than what the timetable promises. Numbers refresh as new flights operate.
