How WN4604 actually runs
Pro Flight Search has tracked every published board update for WN4604 across the DAL and DCA boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left heavily delayed (~47 min) but landed noticeably late (~22 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how WN4604 operates rather than what the timetable promises. Numbers refresh as new flights operate.
