How DL3955 actually runs
Pro Flight Search has tracked every published board update for DL3955 across the SLC and AUS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left noticeably late (~27 min) but landed a little late (~7 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how DL3955 operates rather than what the timetable promises. Numbers refresh as new flights operate.
