Got an email that a DFW/ATL late night segment was canceled. Was rebooked for 7am the next morning. That's a big fat nope and I'm quite sure there would not have been a hotel voucher in the offing.

Why weird? I don't care if I connect in CLT/ORD/elsewhere, Why would the system insist on keeping the same routing?

I was able to change to a CLT routing on the phone, and rather quickly. I was dreading the "your expected wait time is 95 minutes"...
