How SQ33 actually runs

Pro Flight Search has tracked every published board update for SQ33 across the SFO and SIN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left a little late (~8 min) but landed about 13 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how SQ33 operates rather than what the timetable promises. Numbers refresh as new flights operate.
