How DL499 actually runs
Pro Flight Search has tracked every published board update for DL499 across the BOS and DEN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left a little late (~20 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how DL499 operates rather than what the timetable promises. Numbers refresh as new flights operate.
