How UA819 actually runs

Pro Flight Search has tracked every published board update for UA819 across the IAH and EZE boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left noticeably late (~26 min) but landed about 55 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA819 operates rather than what the timetable promises. Numbers refresh as new flights operate.
