How UA2 actually runs
Pro Flight Search has tracked every published board update for UA2 across the SIN and SFO boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: landed -11 min. Not enough to call it.
The verdict above is that record speaking, so it reflects how UA2 operates rather than what the timetable promises. Numbers refresh as new flights operate.
