How WN3959 actually runs

Pro Flight Search has tracked every published board update for WN3959 across the TUL and HOU boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left a little late (~7 min) but landed about 12 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3959 operates rather than what the timetable promises. Numbers refresh as new flights operate.
