How DL851 actually runs

Pro Flight Search has tracked every published board update for DL851 across the LAS and DTW boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: landed -1 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL851 operates rather than what the timetable promises. Numbers refresh as new flights operate.
