Pro Flight Search has tracked every published board update for SQ309 across the LGW and SIN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~22 min) but landed about 20 min early. Not enough to call it.
