By the way, does anyone know how this program interacts with these routings:

(1) A circle trip, entirely in B or higher fare classes? (Would AUS-SMF-RDU-AUS could as 1.5 points?)

(2) An itinerary that includes legs in both B or higher, and discount fares? (For example, an outgoing flight in H and a returning fare in S.)

(3) A single day's travel that includes higher and discount fares? (For example, an AUS-ROC routing that includes AUS-IAH in I and IAH-CLE-ROC in H.)
