How UA129 actually runs

Pro Flight Search has tracked every published board update for UA129 across the IAH and GIG boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: departed +52 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA129 operates rather than what the timetable promises. Numbers refresh as new flights operate.
