How UA324 actually runs
Pro Flight Search has tracked every published board update for UA324 across the ATL and ORD boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left noticeably late (~23 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how UA324 operates rather than what the timetable promises. Numbers refresh as new flights operate.
