I took this route (SQ 23/24) and the SIN-EWR route (SQ21/22) quite often. On both routes SIA assign 6 flight deck officers (triple crew?), so each pair can get enough rest. They also assign 10+ cabin attendants to take care of only ~150 passengers. I saw these crew quite often in the terminals of SIN, JFK, EWR, as it is really hard to miss such a big crowd. Maybe the A380 crew has a larger cabin team, but six people wearing pilot uniforms is eye-catching. The SG aviation rules say no less than four pilots: www.caas.gov.sg/docs/default-source/pdf/ac121-11-2(rev-0)-fatigue-risk-management-for-ulr-operations.pdf
