Although Paulding County’s airport northwest of Atlanta has been getting lots of attention lately for its plan to attract commercial airline service, there are several other small airports in the metro area that are used every day by businesses, pilots, flight schools and public safety services.

“There’s a huge economic impact that unless you work in general aviation or your business depends on general aviation, you may not be aware of it,” said Selena Shilad, executive director for the Alliance for Aviation Across America. “There are a lot of important services as well that depend on general aviation, and when those service providers cannot get out of major commercial airports it makes a lot of sense for them to use those general aviation airports.”

Hartsfield-Jackson International, the world’s busiest airport, remains the behemoth of Georgia generating $58 billion in economic output. Georgia’s public general aviation airports, totaling 95, generate $1.2 billion.

Paulding County’s airport this month revealed a plan to attract limited airline service. That’s not the case for these other metro Atlanta’s small airports. Still, there’s plenty going on at these sites. Here’s a breakdown of six small airports within 30 miles of downtown Atlanta.
