How AC509 actually runs
Pro Flight Search has tracked every published board update for AC509 across the YYZ and ORD boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left right on schedule but landed about 8 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how AC509 operates rather than what the timetable promises. Numbers refresh as new flights operate.
