How AS420 actually runs

Pro Flight Search has tracked every published board update for AS420 across the SEA and MCO boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: landed +25 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how AS420 operates rather than what the timetable promises. Numbers refresh as new flights operate.
