How AC740 actually runs
Pro Flight Search has tracked every published board update for AC740 across the SFO and YYZ boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs 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 AC740 operates rather than what the timetable promises. Numbers refresh as new flights operate.
