I'm glad I didn't start a new thread about this now LOL. Thanks to everyone for their advice here. I was a little concerned about the 50 minute connection time my TA just booked us next January. I'll still be concerned until we board the o/b flight, but at least I know 50 minutes isn't out of the ordinary.
One question though. I noticed somebody saying Delta will change gates and concourses for a flight pretty frequently, so trying to keep an eye out for a trend with our LAX-ATL flight is pointless. But what about the feeder flights? We are flying to Flint on ASA. Do the feeder lines have a dedicated area, or do they get put all over the place too?
