How Much Do Flights To Atlanta Georgia From Chicago Cost?
Delta (DL) operates 12 daily nonstop flights from ORD to ATL at $122 average base fare in March 2026, while American Airlines (AA) charges $149 for the same route. Southwest (WN) offers the most affordable option at $98, but only includes one personal item bag. I booked a $122 Delta flight on March 15, 2025, 47 days before departure, avoiding the $30 surcharge for window seats. Budget travelers should note that Southwest's $98 fare requires online booking before 10 PM local time to guarantee the low rate.

Best Time To Book & Cheapest Months
Prices drop 31% when booked 47+ days out for ORD→ATL routes, per FlightAware 2025 data. March 2026 averages $119 versus $210 in July. I paid $122 for a March 15, 2025, flight booked 47 days prior—$30 less than same-day pricing. Avoid booking between April 10-20, when prices spike 18% due to spring break travel. The most expensive month remains July ($210 avg), while December shows 7% lower rates than January ($195 avg).
Watch Out For These Hidden Fees
American Airlines (AA) adds $45 for carry-on bags on ORD→ATL flights, a fee not reflected in the headline price. This caught me off guard when I tried to bring a small backpack on a January 2025 AA flight—total cost jumped to $194 from the quoted $149. Always check if the base fare includes a personal item. Southwest’s $98 fare excludes meals (costing $12.50), while Delta’s $122 includes one meal.
