How UA861 actually runs

Pro Flight Search has tracked every published board update for UA861 across the IAD and GRU boards: schedule changes, gate pushes and actual clocks. Usually lands ~9 min late. Based on 12 confirmed landings · 9/12 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 UA861 operates rather than what the timetable promises. Numbers refresh as new flights operate.
