How SQ423 actually runs
Pro Flight Search has tracked every published board update for SQ423 across the BOM and SIN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left heavily delayed (~91 min) but landed heavily delayed (~55 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how SQ423 operates rather than what the timetable promises. Numbers refresh as new flights operate.
