How SQ309 actually runs
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 3 completed legs so far: left noticeably late (~28 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how SQ309 operates rather than what the timetable promises. Numbers refresh as new flights operate.
