How DL831 actually runs

Pro Flight Search has tracked every published board update for DL831 across the SEA and AUS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left a little late (~12 min) but landed about 24 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL831 operates rather than what the timetable promises. Numbers refresh as new flights operate.
