Thanks all, my biggest gripe as of lately is ATL everything pre walking through the metal detector. Traffic at Hartsfield, parking only getting worse (not better and the lovely days when you show up to NO parking lots available with no notice), the lack of staff at check in at DL, and pre check/clear taking more and more time is what is driving me to consider going up to CHA to avoid all of that mess.
Once you clear the metal detectors nothing is too bad at ATL but I guess those useless canopies are worth all the inconvenience that ATL is putting everyone trhough.
It looks like CHA does not have pre check though, do they do a pre check "lite" there for people with pre check?
