How UA487 actually runs
Pro Flight Search has tracked every published board update for UA487 across the ORD and BOS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left noticeably late (~41 min) but landed noticeably late (~26 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how UA487 operates rather than what the timetable promises. Numbers refresh as new flights operate.
