How OS439 actually runs

Pro Flight Search has tracked every published board update for OS439 across the VIE and BIO boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left right on schedule but landed about 19 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how OS439 operates rather than what the timetable promises. Numbers refresh as new flights operate.
