How G4438 actually runs

Pro Flight Search has tracked every published board update for G4438 across the HOU and VPS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~122 min) but landed heavily delayed (~95 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how G4438 operates rather than what the timetable promises. Numbers refresh as new flights operate.
