How UA4358 actually runs

Pro Flight Search has tracked every published board update for UA4358 across the IAD and BUF boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~171 min) but landed heavily delayed (~142 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how UA4358 operates rather than what the timetable promises. Numbers refresh as new flights operate.
