How WN737 actually runs
Pro Flight Search has tracked every published board update for WN737 across the PHX and HOU boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left heavily delayed (~90 min) but landed noticeably late (~31 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how WN737 operates rather than what the timetable promises. Numbers refresh as new flights operate.
