The Wright amendment and its restriction on flights out of Dallas Love Field were meant to protect business at Dallas-Forth Worth International Airport. The amendment was introduced in 1979 by Congressman Jim Wright, who represented the Fort Worth area.
Southwest officials have lobbied for the law's repeal for years. The restrictions were partially lifted in 2006, when Southwest began one-stop flights from Dallas to BWI.
The full repeal of the restrictions "signifies a turning point for the Southwest brand not just in Dallas, but from coast-to-coast," said Gary Kelly, Southwest Airlines president and CEO, in a statement.
"Goodbye, Wright Amendment. Hello, America," he said.
On Nov. 2, Southwest will begin non-stop flights from Dallas to 10 additional airports, including Ronald Reagan Washington National Airport.
