How UA63 actually runs

Pro Flight Search has tracked every published board update for UA63 across the GRU and IAH boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left noticeably late (~45 min) but landed about 20 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA63 operates rather than what the timetable promises. Numbers refresh as new flights operate.
