How OU440 actually runs

Pro Flight Search has tracked every published board update for OU440 across the ZAG and VIE boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left a little late (~9 min) but landed about 9 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how OU440 operates rather than what the timetable promises. Numbers refresh as new flights operate.
