To quote Dizel8, exactly.
Nobody wanted to operate out of Love because of the restrictions, that is other than SWA and a few other token flights on other carriers. However, now that the restrictions are going away, other carriers may want to serve Love, but seeing that this could happen, AA and SWA have colluded to make sure there is no availability of gates, essentially giving SWA a private airport.
To further make sure no carrier can make inroads, the gates are being demolished. Now, this may be a good compromise for AA and SWA, but for all other carriers it isn't. Hats off to them for pulling it off, however, even the most ardent SWA fan can see, that this benefits SWA and that as a company, they are making sure no one else can join the show at Love.
I am sure SWA would be most upset, if an airport they were trying to serve, say DIA, had seen UAL and Frontier lock them out and destroy gates, even though there were room.
Like I said, smart ploy by SWA, but in the big scheme of things, probably not the best move from the goverment vis a vis anticompetetive.
