How OS42 actually runs
Pro Flight Search has tracked every published board update for OS42 across the IAD and VIE boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left a little late (~20 min) but landed about 6 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how OS42 operates rather than what the timetable promises. Numbers refresh as new flights operate.
