Thanks, travelingdrsuz and TWA884. Yup, I'm aware the connection would be on my own, so a chance I'd have to rebook. And I'll check on the DL forum as suggested for getting around ATL from Terminal F. Since I'll have to go outside to baggage claim, I'm sure I won't end up in the sterile area. Or at least won't be able to stay there.
