How DL42 actually runs

Pro Flight Search has tracked every published board update for DL42 across the SEA and FCO boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: landed -21 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL42 operates rather than what the timetable promises. Numbers refresh as new flights operate.
