One must understand the city of ATL to understand that they can, will and have been bought......basically defines their M.O. The fill dirt of the new runway was built on back door shady deals. A literal mountain of kick backs and bribes. The airport is basically the only thing keeping the city from financial ruin, due to years of inep management and corruption.
I wouldn't be surprised if the city drew "SWA" on their foreheads while building a new terminal for them ( for the right price) SWA is great at giving the perception of value to consumers and politicians. Can't blame them for that.
Building a terminal is one thing. The flow of traffic in ATL is another thing. They'll see.
