I doubt AA has many fans in Missouri. A lot of folks took a hit when AA took over TWA.
This will get SWA two metro markets from Dallas. Tennessee should probably be next on the list.
These large cities have at least 2 airports without a Wright-type amendment. New York, Chicago, LA, Houston, SF/Oak, Wash D.C. None of these airports are threatened.
I live in Dallas...DFW represents big, overbloated govt. Love Field runs lean and mean plus easy access in and out. American Airlines has lots of snooty employees...not so with SouthWest....very nice and friendly and no penalty fees to change flights. Screw the Wright Amendment. DFW airport will survive just fine. SET LOVE FREE.
