American Airlines is the dominant carrier at Dallas/Fort Worth International Airport (DFW) and utilizes all five current terminals (A, B, C, D, and E) to some extent. However, its primary operations are centered in Terminals A, B, and C, which are almost exclusively American Airlines gates. Terminal D is used for most of their long-haul international departures and arrivals due to the customs facilities, while Terminal E hosts some of their regional "American Eagle" flights. In 2026, a major expansion is underway for Terminal F, which will eventually become a signature, all-American Airlines terminal with 15+ new gates to support their massive growth in North Texas. To move between these terminals, passengers use the Skylink high-speed train, which runs every 2 minutes inside the secure area, making even "cross-terminal" connections manageable within 15–20 minutes.
