How WN317 actually runs

Pro Flight Search has tracked every published board update for WN317 across the HOU and CUN boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left about 5 min early but landed about 15 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN317 operates rather than what the timetable promises. Numbers refresh as new flights operate.
