How G4554 actually runs

Pro Flight Search has tracked every published board update for G4554 across the PHL and GRR boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left about 10 min early but landed about 24 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how G4554 operates rather than what the timetable promises. Numbers refresh as new flights operate.
