How DL79 actually runs
Pro Flight Search has tracked every published board update for DL79 across the PRG and JFK boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left a little late (~8 min) but landed about 21 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how DL79 operates rather than what the timetable promises. Numbers refresh as new flights operate.
