Part of the reason it is so darn expensive to fly in and out of Dallas is because of something called the Wright Amendment, which is set to expire in 2014. When DFW airport was built, the Wright Amendment stated that any airline that flew in and out of Dallas Love Field (DAL) had to make one stop if it flew more than one state away (further than the states bordering Texas). This stupid agreement was made so that DFW airport had a chance to "survive" and get its business up and running, but it limited competition in our area. Southwest stayed at DAL and has made a great business, you just have to make a stop if you are going outside that one-state border. Same rule applies coming into DAL. There are lots of airlines going in and out of DFW, though, so not sure why they are so expensive, unless DFW is an expensive airport in terms of fees.
