How WN4322 actually runs
Pro Flight Search has tracked every published board update for WN4322 across the HOU and MDW boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left noticeably late (~24 min) but landed a little late (~6 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how WN4322 operates rather than what the timetable promises. Numbers refresh as new flights operate.
