How AA1146 actually runs

Pro Flight Search has tracked every published board update for AA1146 across the BOS and PHL boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left noticeably late (~33 min) but landed right on schedule. Not enough to call it.

The verdict above is that record speaking, so it reflects how AA1146 operates rather than what the timetable promises. Numbers refresh as new flights operate.
