Charlotte doesn't get much nonstop long-haul international traffic. From DOT, here's a list of total enplanements on nonstop routes to Europe and South America between 1/1/2013 and 6/20/3013:

I also pulled all Charlotte domestic traffic on Star Alliance and One World carriers, including US/UA/AA-affiliated regional carriers. By my count, roughly 29% of Charlotte's total OW/*A traffic - including both O&D and connecting passengers - comes from airports for which Charlotte is arguably more convenient than, or as convenient as, any other US/AA hub for many connections. This data covers 1/1/2013 to 9/30/2013:
