How WN18 actually runs
Pro Flight Search has tracked every published board update for WN18 across the HOU and CHS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left right on schedule but landed about 14 min early. Not enough to call it.
