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. Usually lands ~13 min early. Based on 4 confirmed landings · 3/4 within 15 min of schedule. Pushes back late but makes up time in the air.

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.
