How OS401 actually runs
Pro Flight Search has tracked every published board update for OS401 across the VIE and BCN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left a little late (~10 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how OS401 operates rather than what the timetable promises. Numbers refresh as new flights operate.
