As of 2026, Charlotte Douglas International Airport (CLT) does not have a separate, standalone international terminal. Instead, it operates under a "single terminal" concept where all five concourses (A through E) are connected behind a single security perimeter. Concourse D serves as the primary gateway for international arrivals and departures. While you depart for international destinations from Concourse D just like a domestic flight, arriving international passengers are routed through a secure "sterile corridor" that leads to the U.S. Customs and Border Protection (CBP) facility located on the lower level of the terminal. This layout is particularly efficient for those connecting from an international flight to a domestic American Airlines flight, as they don't need to change buildings; however, it does mean that the "international" experience is integrated into the main airport hub. Recent expansions in 2025 have added more wide-body gates to Concourse A and D to handle increased transatlantic traffic, but the "one roof" philosophy remains the core of CLT's design.
