For a connection at Charlotte Douglas International Airport (CLT) in 2026, you should allow a minimum of 60 to 90 minutes for a domestic-to-domestic flight. Although CLT is often praised for its compact, single-terminal design where you can walk between the farthest gates in about 15 minutes, the airport is operating at record-breaking capacity in 2026, leading to frequent "ramp congestion" that can delay deplaning. If you are connecting from an international flight to a domestic one, you should allow at least 3 hours to clear U.S. Customs and Border Protection, collect your bags, and re-clear TSA security. For those seeking a "no-stress" experience, a 2-hour window is the "gold standard" for domestic connections, providing enough time to navigate the crowds in the central atrium and account for the common 15-minute taxi delays that occur at this major American Airlines hub.
