How SQ517 actually runs

Pro Flight Search has tracked every published board update for SQ517 across the CCU 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 (~29 min) but landed about 12 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how SQ517 operates rather than what the timetable promises. Numbers refresh as new flights operate.
