I have considered SQ12 (SIN-NRT-LAX) for the flight home but that leaves us with a coach flight from LAX to IAD to finish it off which sucks. If we did choose that flight, would we be able to stopover in NRT? I would love to see Tokyo. Also, could we possibly take SQ12 in C from SIN to NRT and then get another flight from NRT to IAD also in C?
