How AC2421 actually runs

Pro Flight Search has tracked every published board update for AC2421 across the LHR and YYC boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left a little late (~11 min) but landed about 20 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how AC2421 operates rather than what the timetable promises. Numbers refresh as new flights operate.
