How OS41 actually runs
Pro Flight Search has tracked every published board update for OS41 across the VIE and IAD boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left heavily delayed (~48 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how OS41 operates rather than what the timetable promises. Numbers refresh as new flights operate.
