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. The joint airport proposal was revisited in 1961 after the Federal Aviation Administration (FAA) refused to invest more money in separate Dallas and Fort Worth airports. While airline service had steeply declined at both GSW and Meacham, Dallas Love Field was congested and had no more room to expand. Following an order from the federal government in 1964 that it would unilaterally choose a site if the cities could not come to an agreement, officials from the two cities finally agreed on a location for a new regional airport that was north of the near-abandoned GSW and almost equidistant from the two city centers. The land was purchased by the cities in 1966 and construction began in 1969. Voters went to the polls in cities throughout the Dallas–Fort Worth metroplex to approve the new North Texas Regional Airport, which was named after the North Texas Commission that was instrumental in the regional airport coming to fruition. The North Texas Commission formed the North Texas Airport Commission to oversee the planning and construction of the giant airport. Area voters approved the airport referendum and the new North Texas Regional Airport would become a reality. However, many Dallas residents remained satisfied with Love Field, and an attempt to establish an independent Dallas Fort Worth Regional Airport Authority—despite strong backing from the Dallas Chamber of Commerce and Dallas mayor J. Erik Jonsson—failed when Dallas voters rejected the proposal by a narrow margin. After further negotiation, the cities instead established an appointed airport board consisting of seven members from Dallas and four from Fort Worth and were able to persuade all existing air carriers at Love and GSW to move to the new regional airport. Under the original 1967 airport design, DFW was to have pier-shaped terminals perpendicular to a central highway. In 1968, the design was revised to provide for semicircular terminals, which served to isolate loading and unloading areas from the central highway, and to provide additional room for parking in the middle of each semicircle. The plan proposed thirteen such terminals, but only four were built initially. Opening and
