How WN3644 actually runs

Pro Flight Search has tracked every published board update for WN3644 across the MSY and HOU boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~183 min) but landed a little late (~12 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3644 operates rather than what the timetable promises. Numbers refresh as new flights operate.
