Situated in the Texas prairie between the major cities of Dallas and Fort Worth, DFW airport, the third largest airport in the world, may be quite familiar to American Airlines passengers. It's the airline's headquarters and a major point for flight transfers and aircraft movements.

No, Dallas/Fort Worth International Airport (DFW) is not the biggest airport in the world by land area or passenger traffic, although it is undeniably massive. By land area, the largest airport in the world is King Fahd International Airport (DMM) in Saudi Arabia, which spans an incredible 299 square miles—larger than the neighboring country of Bahrain. DFW ranks as the second-largest in the United States (behind Denver) and usually sits in the top five globally for land area, covering about 27 square miles. In terms of passenger traffic, Hartsfield-Jackson Atlanta (ATL) consistently holds the title of the busiest airport in the world. DFW is a "high-fidelity" mega-hub, serving as the primary base for American Airlines and featuring its own zip code, police force, and a highly efficient "Skylink" train that connects its five terminals. While not the #1 "biggest" in any single category, it is one of the only airports in the world that currently has seven operational runways, giving it a flight-handling capacity that few others can match in 2026.
