How KL1991 actually runs
Pro Flight Search has tracked every published board update for KL1991 across the AMS and LJU boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left heavily delayed (~50 min) but landed about 9 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how KL1991 operates rather than what the timetable promises. Numbers refresh as new flights operate.
