How WN4123 actually runs

Pro Flight Search has tracked every published board update for WN4123 across the LGB and PHX boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left a little late (~11 min) but landed about 17 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN4123 operates rather than what the timetable promises. Numbers refresh as new flights operate.
