How DL125 actually runs
Pro Flight Search has tracked every published board update for DL125 across the LIS and BOS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left heavily delayed (~169 min) but landed about 11 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how DL125 operates rather than what the timetable promises. Numbers refresh as new flights operate.
