You also have SFO-NRT-SIN/BKK(NH)-DPS(SQ/TG), and SFO-HKG(UA)-SIN/BKK-DPS(SQ/TG), as well as the way I am getting to DPS (but I start out in SEA first): SFO-NRT(UA)-HKG(NH)-SIN-DPS(SQ). I am taking a stopover in HKG (and in BKK on the return to HKG) because I am daisy-chaining a CO South Asia J redemption on top of a US North Asia F one.

Plus you have OZ: SFO-ICN(OZ)-SIN-DPS(SQ), or connecting in BKK via TG, or routing through LAX or SEA... oh, and don't forget, there's SFO-SEA-NRT on UA...
