The Georgia hub of Hartsfield-Jackson Atlanta International Airport (ATL) has, pandemic aside, long been known as the busiest airport in the world by passenger numbers. However, while this provides airlines with a large market to work with, it is also a market defined by intense competition, meaning that, despite its promise, Atlanta can be a tough nut to crack. This is evidenced by Southwest.

Indeed, by looking at scheduling data from January 2022 to June 2026 and comparing these results to what is available from July 2026 onwards, we can see that Southwest Airlines has cut no fewer than 26 routes from Atlanta, according to aviation data and analytics firm Cirium.

As detailed in the map above, Southwest’s cuts in Atlanta have a broad spread. Most, however, pertain to destinations in the center and east of the US, with the only West Coast routes to be shelved being Los Angeles, Oakland, and San Diego. Contrastingly, Florida alone has lost eight routes: Fort Lauderdale, Fort Myers, Jacksonville, Miami, Panama City, Pensacola, Sarasota, and West Palm Beach.

To the north, Southwest no longer serves Atlanta from Cleveland, Louisville, Milwaukee, New York, Omaha, Philadelphia, Raleigh-Durham, Richmond, and Washington, DC. Elsewhere, Greenville, Jackson, Little Rock, Memphis, Myrtle Beach, and Oklahoma City have also been shelved. Southwest first began flying to and from Atlanta back in 2012. Then-CEO Gary Kelly explained the importance of the airline’s presence at ATL.

“Our service from Atlanta brings greatly reduced fares with new flexibility and value for both leisure and business customers.”

How Has Southwest’s Presence In Atlanta Changed Over The Years?

Southwest’s initial growth at ATL was slow and steady. Indeed, after scheduling 7,498 flights from the Georgia hub in 2012, this figure only grew to 9,996 in 2013. However, 2014 saw its first true boom in Atlanta, with this figure more than doubling to 21,416 scheduled departures. These offered 3,060,796 seats and 2,684,303,378 ASMs.

Still, Southwest wasn’t done growing there, and 2015 saw its total more than double once again to an all-time high of 43,909 flights. For the next few years, this total then remained relatively steady, dropping gradually to 43,573 in 2016, 42,865 in 2017, 42,715 in 2018, and 40,550 in 2019. Then, in 2020, the coronavirus pandemic hit the aviation industry, and the figure dropped more sharply to 29,278.

Following a slight uptick to 29,809 flights in 2021, Southwest’s Atlanta capacity then began rebounding more robustly, climbing to 31,603 flights in 2022 and reaching a post-pandemic peak of 36,677 departures in 2023. Since then, however, this figure has been on the decline, falling gently to 33,523 flights in 2024, but then more dramatically to 21,505 departures in 2025, and now just 16,214 services in 2026.

With that being said, Southwest Airlines is still one of the key players in Atlanta. Indeed, Cirium data show that this month it ranks third at the Georgia hub for scheduled one-way departures (behind Delta Air Lines and Frontier Airlines), with 1,313 flights scheduled. Collectively, these services, whose routes are detailed in the map above, will offer a total of 210,205 seats and 145,690,010 available seat miles, with Southwest also ranking third by these metrics.

The blue-clad budget giant’s top route from Atlanta this month serves Chicago Midway 135 times, although it is pushed close by Baltimore, which will see 132 Southwest departures from Atlanta. Its Texan bases at Dallas Love Field and Houston Hobby are also popular, with each set to be served by a grand total of 116 Southwest flights apiece from Atlanta this month. Contrastingly, Cancun, its only international destination, has just four flights (one a week).
