How SQ631 actually runs

Pro Flight Search has tracked every published board update for SQ631 across the HND and SIN boards: schedule changes, gate pushes and actual clocks. Usually lands ~26 min early. Based on 5 confirmed landings · 5/5 within 15 min of schedule. Pushes back late but makes up time in the air.

The verdict above is that record speaking, so it reflects how SQ631 operates rather than what the timetable promises. Numbers refresh as new flights operate.
