How OS31 actually runs

Pro Flight Search has tracked every published board update for OS31 across the VIE and BOS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: departed +26 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how OS31 operates rather than what the timetable promises. Numbers refresh as new flights operate.
