How OS431 actually runs
Pro Flight Search has tracked every published board update for OS431 across the VIE and VLC boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left heavily delayed (~115 min) but landed heavily delayed (~98 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how OS431 operates rather than what the timetable promises. Numbers refresh as new flights operate.
