AD PLACEMENT — CONTEXTUAL
Check your gate on arrival screens immediately since American frequently reassigns gates during peak banks.
If connecting from an international flight, budget extra time for the CBP process at the Concourse A international arrivals facility before you can walk to other concourses.
Concourse E gates are the farthest walk from A and B, so allot extra time if your connection spans those ends.
Use the moving walkways in the connecting corridors to save time between concourses.
Peak banks around 7-9am and 4-8pm see the heaviest congestion, so tighter connections are riskier during those windows.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
There is no train or shuttle between concourses at CLT; passengers walk through connecting corridors and atriums, aided by moving walkways in the longer stretches. International arrivals clear Customs and Border Protection at the dedicated Concourse A international arrivals facility, and a sterile corridor allows onward domestic connections without a second TSA screening.
