How UA771 actually runs

Pro Flight Search has tracked every published board update for UA771 across the LAX and PEK boards: schedule changes, gate pushes and actual clocks. Usually lands ~10 min early. Based on 1 confirmed landing · 1/1 within 15 min of schedule. Pushes back late but makes up time in the air.

The verdict above is that record speaking, so it reflects how UA771 operates rather than what the timetable promises. Numbers refresh as new flights operate.
