Thank you but I personally feel 74 minutes is taking a huge gamble to clear and make the connection.
If you have Global Entry and don't have to wait for checked baggage in CLT, then that's enough time to connect. Of course, that assumes you leave SXM on time. Were it me, I'd book it. CLT is a very easy airport to navigate, and their immigration area is very efficient. However, waiting for baggage there is always a problem, so I wouldn't do it if I had checked bags.
