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: landed +10 min. 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.
