How DL2639 actually runs

Pro Flight Search has tracked every published board update for DL2639 across the JFK and BOS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left about 5 min early but landed about 37 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL2639 operates rather than what the timetable promises. Numbers refresh as new flights operate.
