Quite a few of them are though. Look at SAN-GEG tomorrow. XJT is $586 round trip, and while others offer less, the only non-stop flight is on XJT.

So far I'm very happy with the Branded results. And if you look at load factor by route, you'll see that a lot of the low load routes are in the east and midwest. If I were to peer into my crystal ball, I would guess that SAT as a domicile may be shrinking soon (if it isn't already?) in order to concentrate more on underserved west coast routes.
