How AC8603 actually runs

Pro Flight Search has tracked every published board update for AC8603 across the BOS and YUL boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left right on schedule but landed about 15 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how AC8603 operates rather than what the timetable promises. Numbers refresh as new flights operate.
