Southwest Airlines, known for its low fares and customer-friendly policies, is one of the largest domestic carriers in the United States. If you're planning a trip and flying with Southwest, understanding its hub system can make your travel smoother and more efficient. In this article, FaresMatch breaks down the major Southwest hubs, their key features, and how they benefit travelers.

What Is a Southwest Hub?

Unlike traditional airlines that operate under a centralized hub-and-spoke model, Southwest Airlines uses a point-to-point system. However, the airline still relies on several key airports as "focus cities" or de facto hubs to manage high traffic volume and offer better connectivity. These hubs are crucial for scheduling, maintenance, and connecting flights.
