The issue you're running into is likely caused by married segment logic, which SQ is far from alone in practicing. You didn't book JFKFRA + FRASIN + SINDPS individually, but JFKDPS. SQ may have released award space for JFKDPS but not JFKSIN and SINDPS. In other words, it's all-or-nothing if you're trying to change the itinerary.
It's also possible - given the state of SQ's call centre - that the agent is inexperienced and those segments aren't married. You'll have to HUACA to find out, as frustrating as it sounds.
Fair points. What I am certain of, is that after ticketing JFKHKGDPS on CX, I can freely adjust JFKHKG without making changes to HKGDPS, even when no incremental awards are available on HKGDPS, as long as my HKG layover doesn’t exceed the allotted time. As I can, with similar itineraries, on BA, AA, DL, JL, ET and KE, to name a few. It’s unfortunate (for me) that SQ doesn’t fall into this category. I could purchase SINDPS to solve for this, but I don’t think it’s worth it just to avoid a stop in FRA. I respect that airlines aren’t sensitive to inflight products, but it’s still disappointing that SQ won’t show some flexibility given the loss of the 380. I never would have selected a direct flight on the 77W…my choice was solely a function of the 380.
