How WN3677 actually runs

Pro Flight Search has tracked every published board update for WN3677 across the SAN and SFO boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~45 min) but landed noticeably late (~32 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how WN3677 operates rather than what the timetable promises. Numbers refresh as new flights operate.
