SWA is sometimes competitive, though it is increasingly rare. Before the Fall Florida sale, they were consistently higher than both NWA and Spirit (both of which fly direct) for our September weekend. The fall sale, though, was a really good deal if you grabbed it.
Even the DTW/MCO dings (which are rare) are often not good deals. I fly out of DTW, and ended up removing DING---I was rarely getting good prices to anywhere at all. The normal SWA sales seem to be better in this market.
