What is the primary hub for American Airlines?

The primary hub for American Airlines is Dallas/Fort Worth International Airport. This airport serves as the central hub for the airline's operations, providing a critical connection point for domestic and international flights. Dallas/Fort Worth is strategically located in the central United States, allowing for efficient access to various destinations across the country and around the globe. The airport supports a significant volume of American Airlines flights and accommodates a wide range of services, including maintenance and cargo operations.

The other options represent major airports with significant operations, but they do not function as American Airlines' primary hub. For instance, while Chicago O'Hare is one of the busiest airports and a key location in American Airlines' network, it serves more as a secondary hub compared to Dallas/Fort Worth. Likewise, John F. Kennedy International Airport and Los Angeles International Airport are important for international and domestic services but do not encompass the scale of operations that define Dallas/Fort Worth as the airline's main hub.
