How DL437 actually runs

Pro Flight Search has tracked every published board update for DL437 across the LAX and BOS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left right on schedule but landed about 15 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL437 operates rather than what the timetable promises. Numbers refresh as new flights operate.
