Washington Post columnist George F. Will adds this column to the growing body of opinion that the Wright Amendment — which restricts Southwest Airlines from flying to most states from its Dallas Love Field hub — is at least obsolescent and probably bad public policy in the first place. Here are previous posts on the Wright Amendment.
In his column, Mr. Will passes along a humorous anecdote from Herb Kelleher, Southwest’s chairman, regarding the Wright Amendment and the beginning of the airline:

In 1971, after years of harassing litigation by two airlines averse to competition, Southwest Airlines was born. It had just three aircraft and flew only intrastate, between Dallas, Houston and San Antonio. This first of the no-frills, low-cost airlines, under the leadership of its ebullient founder Herb Kelleher, was to democratize air travel and revolutionize the airline industry.
The cities of Dallas and Fort Worth, and the Dallas/Fort Worth airport, which opened in 1974, tried unsuccessfully to force Southwest to move its operations from close-in Love Field out to DFW, arguing that the new airport depended on this. Today Kelleher laughingly recalls telling a judge:

“If a three-aircraft airline can bankrupt an 18,000-acre, nine-miles-long airport, then that airport probably should not have been built in the first place.”
