operations DFW held an open house and dedication ceremony on September 20–23, 1973, which included the first landing of a supersonic Concorde in the United States, an Air France aircraft en route from Caracas to Paris. The attendees at the airport's dedication included former Texas Governor John Connally, Transportation Secretary Claude Brinegar, U.S. Senator Lloyd Bentsen and Texas Governor Dolph Briscoe. The airport opened for commercial service as Dallas/Fort Worth Regional Airport on January 13, 1974, at a cost of $700 million. At the time of DFW's opening, at 17,500 acres (27.3 sq mi), it was the largest airport in the world ever constructed in terms of land area (surpassed in October 1975 with the opening of Montréal-Mirabel International Airport). The first flight to land was American Airlines Flight 341 from New York, which had stopped in Memphis and Little Rock. The surrounding cities began to annex the airport property into their city limits shortly after the airport was developed. The name change to Dallas/Fort Worth International did not occur until 1985. An innovative feature of the airport during its early history was the Vought Airtrans, the world's first operational fully automated people mover system. Later rebranded as the Airport Train and the TrAAin ("AA" signifying American Airlines), the system ultimately encompassed of fixed guideways and transported as many as 23,000 persons per day at a maximum speed of . When it opened, DFW had four terminals, numbered 2W, 2E, 3E and 4E. During its first year of operations, the airport was served by American Airlines, Braniff International Airways, Continental Airlines, Delta Air Lines, Eastern Air Lines, Frontier Airlines, Ozark Air Lines, Rio Airways and Texas International Airlines. The Wright Amendment of 1979 banned long-distance flights into Love Field, leaving Southwest Airlines as Love Field's only jet airline and operating solely as an intrastate air carrier in the state of Texas. Braniff International Airways was a major operator at DFW in the airport's early years, operating a hub from Terminal 2W with international flights to South America and Mexico from 1974, London from 1978, and Europe and Asia from 1979, before ceasing all operations in 1982. During the Braniff hub era, DFW was one of only four U.S. airports to have scheduled Concorde service; Braniff commenced scheduled Concorde service from Dallas to Washington from 1979 to 1980, using British Airways and Air France aircraft temporarily re-registered to Braniff while flying
