Delta Air Lines also built up a hub operation at DFW, which occupied most of Terminal 4E through the 1990s. The Delta hub peaked around 1991, when Delta had a 35 % market share at DFW; its share was halved by 2004, after many of its mainline routes were downgraded to more frequent regional jet service in 2003.
Illustration of plans for the airport
Delta closed its DFW hub in 2004 in a restructuring of the airline to avoid bankruptcy, cutting its DFW operation to only 21 flights a day from over 250 and redeploying aircraft to hubs in Cincinnati, Atlanta and Salt Lake City. Prior to the closure, Delta had a 17.3 % market share at DFW. After the closing of Delta ' s hub, DFW offered incentives to Southwest Airlines to relocate its service to DFW from Love Field, but Southwest, as in the past, chose to stay at Love Field. DFW has been a hub for Braniff International Airways, Braniff 2, Delta Air Lines, Frontier Airlines and Texas International Airlines. In 1989 the airport authority announced plans to rebuild the existing terminals and add two runways. After an environmental impact study was released the following year, the cities of Irving, Euless and Grapevine sued the airport over its extension plans, a battle that was finally decided( in favor of the airport) by the US Supreme Court in 1994. The seventh runway opened in 1996. The four primary north – south runways( those closest to the terminals) were all lengthened from 11,388 feet( 3,471 m) to their present length of 13,400 feet( 4,084 m). The first, 17R / 35L, was extended in 1996( at the same time the new runway was constructed) and the other three( 17C / 35C, 18L / 36R and 18R / 36L) were extended in 2005. DFW is now the only airport in the world with 4 serviceable paved runways longer than 4,000 metres( 13,123 ft). Terminal D, built for international flights, and DFW Skylink, a modern bidirectional people mover system, opened in 2005.
