How UA889 actually runs

Pro Flight Search has tracked every published board update for UA889 across the PEK and SFO boards: schedule changes, gate pushes and actual clocks. Usually lands on time. Based on 4 confirmed landings · 2/4 within 15 min of schedule. Pushes back late but makes up time in the air.
