How OS775 actually runs
Pro Flight Search has tracked every published board update for OS775 across the VIE and SOF boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left a little late (~18 min) but landed about 8 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how OS775 operates rather than what the timetable promises. Numbers refresh as new flights operate.
