Southwest only sells tickets directly (another way they keep fares low) and they don't share flight data with Kayak/Priceline/etc.. If Southwest covers your route, their fares are almost always going to be competitive with the lowest price. Where Southwest is not good is when you have longer flights (cross country) which will almost always entail stops and or changing planes. But it is great for short stuff like flying between OAK/LAX/SFO/PHX/LAS.
