Location identifier in the context of Vandenberg Space Force Base

An IATA airport code, also known as an IATA location identifier, IATA station code, or simply a location identifier, is a unique three-letter geocode designating many airports, cities (with one or more airports) and metropolitan areas (cities with more than one airport) around the world, defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.

The assignment of these codes is governed by IATA Resolution 763, and it is administered by the IATA's headquarters in Montreal, Canada. The codes are published semi-annually in the IATA Airline Coding Directory.

Dallas Fort Worth International Airport (IATA: DFW, ICAO: KDFW, FAA LID: DFW) is the primary international airport serving the Dallas–Fort Worth metroplex and the North Texas region, in the U.S. state of Texas.

It is the largest hub for American Airlines, which is headquartered near the airport, and is the third-busiest airport in the world by aircraft movements and the second-busiest airport in the world by passenger traffic in 2022 and 2023, according to the Airports Council International.

The hub that American Airlines operates at DFW is the second-largest single airline hub in the world and the United States, behind Delta Air Lines's hub in Atlanta.

In air traffic control, an area control center (ACC), also known as a center or en-route center, is a facility responsible for controlling aircraft flying in the airspace of a given flight information region (FIR) at high altitudes between airport approaches and departures. In the US, such a center is referred to as an air route traffic control center (ARTCC).

A center typically accepts traffic from—and ultimately passes traffic to—the control of a terminal control center or another center. Most centers are operated by the national governments of the countries in which they are located. The general operations of centers worldwide, and the boundaries of the airspace each center controls, are governed by the International Civil Aviation Organization (ICAO).
