American Airlines has a low one-way fare at $93.10 each way between Los Angeles LAX and Atlanta ATL for departures Tuesdays, Wednesdays and some Saturdays from March 1 through May 17. There are more low fare dates for LAX departures than Atlanta departures, but plenty of opportunities to book a $186.20 round trip fare for one day, three days or longer trips.
This one way fare is about $15 lower than fares were in December for LAX-ATL on American and United when I last wrote about this route on sale.
