How DL4905 actually runs

Pro Flight Search has tracked every published board update for DL4905 across the LGA and STL boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: landed -13 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL4905 operates rather than what the timetable promises. Numbers refresh as new flights operate.
