I'm always amazed that when I fly to the US, if the Trans-Pac is on DL metal it will have posted by the time I've landed in ATL or whatever other port I've left LAX for. Ditto the other way (domestic DL points and SCs will have posted while I was doing the Trans-Pac). Yet if it's a VA flight guaranteed the points won't be there for 3 days. How does VA design a system where its partner points post quicker than its own points on the same itinerary?
