How WN1777 actually runs
Pro Flight Search has tracked every published board update for WN1777 across the DEN and SJC boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left heavily delayed (~77 min) but landed heavily delayed (~61 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how WN1777 operates rather than what the timetable promises. Numbers refresh as new flights operate.
