If covered elsewhere, please point me in the right direction.

I am trying to find a transpacific award routing, possibly other than on DL. Using the Awards/Skyteam method, all transpacific routings return "No Award Availablity/Route Too Complex/Date Out of Range." To test, I found a non-stop DL flight with availability using the Awards/DL method which the Skyteam methid could not find (in June, so within the 10 mo. limit). In the test case, I was searching NRT-SFO, both specific airport codes. Does the fact that that method is powered via AF preclude transpacific routes?

Thanks,
