How AS440 actually runs

Pro Flight Search has tracked every published board update for AS440 across the ANC and SEA boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: departed +6 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how AS440 operates rather than what the timetable promises. Numbers refresh as new flights operate.
