How WN3986 actually runs

Pro Flight Search has tracked every published board update for WN3986 across the BUF and HOU boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left a little late (~19 min) but landed right on schedule. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3986 operates rather than what the timetable promises. Numbers refresh as new flights operate.
