How WN553 actually runs
Pro Flight Search has tracked every published board update for WN553 across the AUS and ONT boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left heavily delayed (~79 min) but landed noticeably late (~41 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how WN553 operates rather than what the timetable promises. Numbers refresh as new flights operate.
