How DL797 actually runs

Pro Flight Search has tracked every published board update for DL797 across the BOS and SEA boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: departed -5 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL797 operates rather than what the timetable promises. Numbers refresh as new flights operate.
