wow! that is pretty complicated! I was thinking more along the lines of a specific trip on a specific day and I thought of instead of the typical published routings maybe I could do much better this way. I looked a few up and there are only slim pickings. The date is december 26 or 27, so that may be why - tight loads on that holiday period. PLus, my city pair has very limited choices to begin with: GRB to HSV. There are some cheap fares, but not on that day. Southwest can take me part way, plus driving the rest, for less than $250. Now, if I could eliminate the driving and fly all the way for that price...... but the cheapest fare is at least $100 more.
