How DL124 actually runs

Pro Flight Search has tracked every published board update for DL124 across the BOS and LIS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left heavily delayed (~125 min) but landed about 22 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL124 operates rather than what the timetable promises. Numbers refresh as new flights operate.
