AA2615 already expected in at 825pm now at C17. A little closer to D5, but still pretty much no way OP will make the connection unless it's also delayed. OP should check reservation to see if AA rebooked them already. Or they'll wait until the misconnect actually happens. I'd recommend tomorrow CLT-RDU-LHR. There are still 7 or more seats left in business on the RDU-LHR leg and 2 left on the CLT-RDU leg.
