Returning revenue pricing isn't enough: it needs to be a single fare component between origin and destination airports. The good news for SGN-CGK-MDC is that GA can, indeed, price this as a single component. I see, for example, fare basis VOXCVNVN on 13 March.
If you confirm it's a published thru-fare, try challenging Delta once again.
There may be some unpublished rule that prohibits DL award travel on GA and VN between those points, sort of a 'because we said so' rule. Published fare, thru fare, and married segment availability have variously been features of AA, DL and UA award redemption for quite some time. With DL, this forum has inferred those requirements from thousands of observations - they aren't explicit rules in the SkyMiles program materials. And AA - another program I know pretty well - plays the same way.
Thanks, this is helpful, FWIW the DPS fares I checked were also non-constructed. I am familiar with AA and UA award rules, but fairly new to DL. Just read the wiki here and went to town.
If DPS / SGN endpoints are arbitrarily prohibited with VN+GA tickets, it stands to reason that Delta won't issue any awards with these two Skyteam members at all, which would be pretty bonkers. Anecdotally, I can't get the search engine to return any, regardless of individual segment award availability (and as discussed, fare publishing). I wonder if anyone here can report success, and if so with what routing?
I will give it a third call and see if I can encourage a different result.
