How WN4288 actually runs

Pro Flight Search has tracked every published board update for WN4288 across the PHX and SMF boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left a little late (~11 min) but landed about 8 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN4288 operates rather than what the timetable promises. Numbers refresh as new flights operate.
