How OS553 actually runs
Pro Flight Search has tracked every published board update for OS553 across the VIE and FCO boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left noticeably late (~21 min) but landed a little late (~10 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how OS553 operates rather than what the timetable promises. Numbers refresh as new flights operate.
