How UA5 actually runs

Pro Flight Search has tracked every published board update for UA5 across the IAH and LHR boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left noticeably late (~27 min) but landed about 5 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA5 operates rather than what the timetable promises. Numbers refresh as new flights operate.
