How DL1655 actually runs

Pro Flight Search has tracked every published board update for DL1655 across the BOS and SFO boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left heavily delayed (~185 min) but landed heavily delayed (~174 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how DL1655 operates rather than what the timetable promises. Numbers refresh as new flights operate.
