As a last resort, you can call. This isn't an error fare, so there's no risk of them killing the deal. I would also recommend calling DL, though I think that DL handles all of AF customer service in the US anyway. They can easily ticket this. That's how I booked mine back last June. I actually called 3 separate times and cancelled and rebooked until I got the exact routing I wanted, and it even included a leg on SA. But depending on your status with DL, you may have a $35 booking fee added.
