I am running a search for *A availability on UA from NYC to ORD for Sun July 14 using the Awards/Star Alliance option with the default setting of JP-ANA +3D.

The latest flight in the list that comes up is for a 17:05 departure. I can see though from a timetable search that there are a couple more UA flights later than this. Am I doing something wrong - or are these later flights somehow "hidden" for award availability through the ANA system?
