How AA108 actually runs

Pro Flight Search has tracked every published board update for AA108 across the BOS and LHR boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left about 7 min early but landed about 47 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how AA108 operates rather than what the timetable promises. Numbers refresh as new flights operate.
