How A3999 actually runs
Pro Flight Search has tracked every published board update for A3999 across the IST and ATH 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 11 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how A3999 operates rather than what the timetable promises. Numbers refresh as new flights operate.
