How G4512 actually runs
Pro Flight Search has tracked every published board update for G4512 across the FLL and SDF boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left heavily delayed (~55 min) but landed noticeably late (~29 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how G4512 operates rather than what the timetable promises. Numbers refresh as new flights operate.
