In Dallas, Southwest still scares the hell out of American Airlines... to the extent that the Wright Amendment is still in force to protect American's dominant position at D/FW airport.  The Wright amendment is an interesting little law from the 70's designed to "protect" American and then fledgling D/FW airport from competition.  American has been paying Jack Abramoff lobbyist clones to ensure that the local city councils and the state congressional representatives keep the measure alive ever since.
For those of you who never fly through Dallas, Southwest cannot make direct flights from Love Field in Dallas to any other state except New Mexico, Oklahoma, Arkansas, Louisiana, and Missouri.  If you want to fly out of this region, you have to first fly to Houston (or stop over in one of these states).  You are further unable to reserve "through tickets," meaning you have to book 2 separate flights on your own.
It's an insane, outdated, antiquated law... and it really needs to die.  It's funny how we talk about Free Trade and the Market Economy, unless we're talking about Drug Companies or Airlines.
