How DL91 actually runs

Pro Flight Search has tracked every published board update for DL91 across the ZRH and ATL boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left right on schedule but landed about 42 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL91 operates rather than what the timetable promises. Numbers refresh as new flights operate.
