How AC321 actually runs

Pro Flight Search has tracked every published board update for AC321 across the YUL and YYC boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left about 6 min early but landed about 37 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how AC321 operates rather than what the timetable promises. Numbers refresh as new flights operate.
