How AA1147 actually runs
Pro Flight Search has tracked every published board update for AA1147 across the BOS and PHL boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left noticeably late (~32 min) but landed noticeably late (~22 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how AA1147 operates rather than what the timetable promises. Numbers refresh as new flights operate.
