They're aren't any consequences. There used to be, but the Wright amendment will be gone in 5-6 years, and then its wide open.

It should be noted that SWA has never tried to keep any airlines out of Love Field. AA began flying MD-80s to Austin, Houston, and STL around 3 years ago. They weren't filling up airplanes and gave up on that after a year or so. I think AE does it twice a day now.

SWA isn't the one who's upset about this. Its the other airlines and DFW who are angry.
