In 1940 the Civil Aeronautics Administration earmarked for the construction of a Dallas/Fort Worth Regional Airport. American Airlines and Braniff Airways struck a deal with the city of Arlington to build an airport there, but the governments of Dallas and Fort Worth disagreed over its construction and the project was abandoned in 1942. After World War II, Fort Worth annexed the site and developed it into Amon Carter Field with the help of American Airlines. In 1953 Fort Worth transferred its commercial flights from Meacham Field to the new airport, which was from Dallas Love Field. In 1960 Fort Worth purchased Amon Carter Field and renamed it Greater Southwest International Airport (GSW) in an attempt to compete with Dallas' airport, but GSW's traffic continued to decline relative to Dallas Love Field. By the mid-1960s Fort Worth was getting 1% of Texas air traffic while Dallas was getting 49%, which led to the virtual abandonment of GSW.
