How UA101 actually runs

Pro Flight Search has tracked every published board update for UA101 across the IAH and SYD boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left heavily delayed (~50 min) but landed about 19 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA101 operates rather than what the timetable promises. Numbers refresh as new flights operate.
