How G4583 actually runs

Pro Flight Search has tracked every published board update for G4583 across the GRR and PHL boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left a little late (~7 min) but landed about 13 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how G4583 operates rather than what the timetable promises. Numbers refresh as new flights operate.
