How WN3435 actually runs

Pro Flight Search has tracked every published board update for WN3435 across the PHX and BOI boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~41 min) but landed a little late (~17 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3435 operates rather than what the timetable promises. Numbers refresh as new flights operate.
