How OS604 actually runs
Pro Flight Search has tracked every published board update for OS604 across the ZAG and VIE boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left right on schedule but landed about 8 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how OS604 operates rather than what the timetable promises. Numbers refresh as new flights operate.
