History Planning As early as 1927, before the area had an airport, Dallas proposed a joint airport with Fort Worth. Fort Worth declined the offer and thus each city opened its own airport, Love Field and Meacham Field, each of which had scheduled airline service. 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
