How WN3673 actually runs

Pro Flight Search has tracked every published board update for WN3673 across the SLC and SAN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left right on schedule but landed about 12 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3673 operates rather than what the timetable promises. Numbers refresh as new flights operate.
