At Charlotte Douglas International Airport (CLT) in 2026, the official Minimum Connection Time (MCT) for domestic-to-domestic flights on a single airline (primarily American Airlines) is typically 40 minutes. However, travel experts in 2026 strongly advise against such short windows. While CLT is a "hub-and-spoke" airport where gates are relatively close, its high volume of traffic often leads to gate congestion and taxi delays. If you are connecting from a regional "Eagle" flight (Concourse E) to a mainline flight (Concourse B or C), it can take 15–20 minutes just to walk between gates at a brisk pace. For international-to-domestic connections, the MCT is significantly longer—usually 90 minutes to 2 hours—to account for clearing Customs and Border Protection and re-checking luggage. In 2026, if your connection is under 60 minutes, you risk missing your flight if the inbound plane is even slightly delayed or if you are seated at the back of the aircraft.
