How HD40 actually runs
Pro Flight Search has tracked every published board update for HD40 across the CTS and HND boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left about 7 min early but landed about 22 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how HD40 operates rather than what the timetable promises. Numbers refresh as new flights operate.
