How DL5740 actually runs

Pro Flight Search has tracked every published board update for DL5740 across the PHL and BOS boards: schedule changes, gate pushes and actual clocks. Usually lands ~26 min early. Based on 4 confirmed landings · 4/4 within 15 min of schedule. Pushes back late but makes up time in the air.

The verdict above is that record speaking, so it reflects how DL5740 operates rather than what the timetable promises. Numbers refresh as new flights operate.
