How AS215 actually runs

Pro Flight Search has tracked every published board update for AS215 across the BOS and SEA boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: landed +30 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how AS215 operates rather than what the timetable promises. Numbers refresh as new flights operate.
