How UA604 actually runs

Pro Flight Search has tracked every published board update for UA604 across the SFO and PHL boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: landed -5 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA604 operates rather than what the timetable promises. Numbers refresh as new flights operate.
