How UA4236 actually runs

Pro Flight Search has tracked every published board update for UA4236 across the JAN and HRL boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left right on schedule but landed about 31 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA4236 operates rather than what the timetable promises. Numbers refresh as new flights operate.
