The Wright Amendment is back in the news, as Southwest Airlines (my new favorite carrier—$220 round-trip tickets from JAN to RDU will give you the warm fuzzies, as will non-stop flights to my favorite city in North America) is stepping up its lobbying effort to get the flight restrictions on Dallas’ Love Field repealed.

Vance of Begging to Differ links a study that shows Dallas has the highest airfares of any major U.S. city, and the lack of competition with American Airlines at DFW, particularly now that Delta has shut down its Dallas hub due to its financial problems, is pretty clearly the cause.

American may have also dug itself a bit of a hole in trying to protect its fortress hub at DFW: the Kansas City Star reports that American reneged on promises it made Missouri lawmakers when it took over TWA, and the new chairman of the Transportation Subcommittee of the Senate Appropriations Committee is none other than Kit Bond of Missouri.
