How AA1556 actually runs

Pro Flight Search has tracked every published board update for AA1556 across the BOS and DCA boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~47 min) but landed a little late (~8 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how AA1556 operates rather than what the timetable promises. Numbers refresh as new flights operate.
