For a trip down memory lane, here is a presentation on the City of Dallas' website regarding the AA divestiture and Dallas' attempt to identify who Dallas should favor to win the AA gates.
The city's aviation department has been pro Southwest for years. City Hall, including the council itself, has been pro more-airlines for about as long, egged on by the flying public. To the extent that City Hall gets to tell the aviation dept what to do, their instructions are unequivocal: when this is all over, Delta must stay!
I think all this plan does is kick the can down the road for three years though...
Lift all the remaining restrictions at Love Field (including the ban on international flights) and allow the airlines to build as many gates as they are willing to pay for or is physically possible.
Wishes upon a star for more gates are just that, wishes, however it simply is not going to happen for a very long time. Even if Congress somehow repeals the Wright Amendment Reform Act, the parties to the repeal agreement (cities of Dallas and Ft Worth, American, Southwest and United née Continental) are also contractually bound by its terms. Neither of the three airlines can build more gates at the airport, and while the city of Dallas couldn't necessarily stop another carrier from building additional gates somewhere, the city would be restricted to offer the least amount of support they are legally required to provide, that is they have to issue a construction permit if the request is filed appropriately (after years of lawsuits), and they can't stop the developer from connecting the new building to sewer, utilities, and public roads. When was the last time an airport terminal was built with so little help from the airport owner? New gates are not happening unless Congress does something (ah!) and several courts declare the contract between the parties null and void. By then, a hyperloop will connect downtown Dallas to downtown Houston and Southwest will have lost its cash cow...
