How KL1901 actually runs
Pro Flight Search has tracked every published board update for KL1901 across the AMS and VIE boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left right on schedule but landed about 9 min early. Not enough to call it.
