How G456 actually runs
Pro Flight Search has tracked every published board update for G456 across the LAS and FSD boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left a little late (~16 min) but landed about 5 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how G456 operates rather than what the timetable promises. Numbers refresh as new flights operate.
