How WN51 actually runs
Pro Flight Search has tracked every published board update for WN51 across the DAL and HOU boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left noticeably late (~27 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how WN51 operates rather than what the timetable promises. Numbers refresh as new flights operate.
