How UA29 actually runs
Pro Flight Search has tracked every published board update for UA29 across the SFO and SIN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left a little late (~16 min) but landed about 6 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how UA29 operates rather than what the timetable promises. Numbers refresh as new flights operate.
