How AA856 actually runs

Pro Flight Search has tracked every published board update for AA856 across the BUF and ORD boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left a little late (~19 min) but landed about 16 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how AA856 operates rather than what the timetable promises. Numbers refresh as new flights operate.
