How AS42 actually runs

Pro Flight Search has tracked every published board update for AS42 across the SFO and JFK boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: landed +47 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how AS42 operates rather than what the timetable promises. Numbers refresh as new flights operate.
