How UA1850 actually runs

Pro Flight Search has tracked every published board update for UA1850 across the ATL and ORD boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left a little late (~8 min) but landed about 7 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA1850 operates rather than what the timetable promises. Numbers refresh as new flights operate.
