How WN3919 actually runs

Pro Flight Search has tracked every published board update for WN3919 across the SMF and LAS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left a little late (~16 min) but landed right on schedule. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3919 operates rather than what the timetable promises. Numbers refresh as new flights operate.
