Charlotte Douglas International (CLT) is widely considered one of the easiest major hubs to navigate because of its single-terminal design. Unlike many large airports that require trains or buses to move between terminals, CLT features one central building where all five concourses (A, B, C, D, and E) branch out like spokes on a wheel. This allows passengers to walk to any gate without leaving the secure area. While the airport has grown significantly—housing 114 gates as of 2026—the layout remains compact. Most gate-to-gate walks take between 5 and 15 minutes, though the trek to the far end of Concourse E can take up to 20 minutes. Moving walkways are available in the longer corridors to assist. The airport is also praised for its clear overhead signage and the "CLT Airport" app, which provides real-time maps. For most travelers, the biggest "navigation" challenge isn't the layout, but rather the sheer volume of people, as CLT is a primary hub for American Airlines and can get quite crowded during peak connection windows.
