How AC580 actually runs
Pro Flight Search has tracked every published board update for AC580 across the IAH and YUL boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left a little late (~10 min) but landed about 28 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how AC580 operates rather than what the timetable promises. Numbers refresh as new flights operate.
