Look, if you’re pulling up a flight search engine and typing in "Marietta" as your destination, you're gonna have a bad time. I mean, technically, there’s an airport there. It’s called Dobbins Air Reserve Base. But unless you’re currently serving in the Air Force or you’ve got a very specific military clearance, you aren't landing a commercial jet on that runway. Honestly, I see people get confused by this all the time because some travel sites still list the "MGE" code.
In the real world, finding flights to Marietta Georgia actually means flying into Hartsfield-Jackson Atlanta International Airport (ATL).
It’s about 25 to 30 miles south of Marietta, depending on which part of the city you're headed to. Don’t let the "international" tag intimidate you; it's basically the only gateway for 99% of visitors. Since it's the busiest airport on the planet, you have a weird amount of leverage as a traveler. You’ve got options. You’ve got competition. And, if you play it right, you’ve got some of the cheapest fares in the Southeast.
The Reality of Landing at ATL
When you finally touch down, you aren't "there" yet. Atlanta traffic is a legend for a reason—and not a good one. If you land at 4:30 PM on a Tuesday, that 30-mile drive to Marietta can easily turn into a 90-minute odyssey through a sea of brake lights on I-75.
If you're flying Delta, you’re in their backyard. ATL is their primary hub, which means they run over 1,000 flights a day. You can get a direct flight from nearly anywhere—from London to Los Angeles. But if you’re looking to save some cash for the actual trip, carriers like Southwest, Frontier, and Spirit have massive footprints here too.

Public Transit vs. The "Atlanta Way"
Most locals will tell you to just rent a car. Marietta isn't exactly a "walkable" city once you get outside the historic Square. However, if you're trying to avoid the $100 Uber bill (yeah, it gets that high during surge pricing), you can take MARTA.
- Hop on the Red or Gold rail line directly from the airport terminal.
- Ride it north to the Arts Center Station.
- Transfer to the CobbLinc Bus (specifically Route 10).
It’ll take you about an hour and twenty minutes. It’s a bit of a trek with luggage, but it only costs about $5 to $8 total. Compare that to a rental car that might sit in hotel parking for $30 a day, and the math starts looking pretty good.
When to Actually Pull the Trigger on Tickets
Timing is everything. According to 2026 travel data and historical trends from spots like Skyscanner and Going (formerly Scott’s Cheap Flights), January is usually the cheapest month to fly into the area. The weather is a bit grey and chilly—maybe 45°F—but the flight prices are bottom-of-the-barrel.
If you’re coming for the vibes, aim for the "Goldilocks Window." For domestic flights to Marietta Georgia, that’s roughly 1 to 3 months before you leave. If you see a round trip for under $200 from the West Coast or $120 from the East Coast, grab it. Prices don’t usually "dip" last minute here; they spike because of the massive volume of business travelers heading into the Perimeter and Cobb County.

The Secret Alternative: PDK
Wait, there’s a "secret" option. If you’re fancy—or if you’re traveling for high-level business—you might look at DeKalb-Peachtree Airport (PDK). It’s a general aviation airport. You won’t find Delta or United there, but if you’re using a private charter or a semi-private service like Surf Air, it’s actually a much smoother experience. It’s located in Chamblee, which is a straight shot across I-285 to Marietta. No TSA lines, no "Plane Train," just a quick hop out of the cockpit and into a car.
What Nobody Tells You About the Drive North
Once you exit the airport, you're heading north. You’ll pass through Downtown Atlanta, then Midtown, and finally hit the "Top End" of the Perimeter. This is where things get hairy.
The I-75 North corridor has "Express Lanes." Use them. Seriously. They are reversible toll lanes that can save you an hour of your life during rush hour. You need a Peach Pass to use them legally, but many rental cars come equipped with them. Check with the rental desk. If you don't have one, don't jump in those lanes—the cameras will catch you, and the fine is a nasty surprise to find on your credit card statement a month later.
A Note on the "Other" Airports
I’ve seen some travel blogs suggest flying into Birmingham (BHM) or Chattanooga (CHA) and driving in.

Don't do that.
Unless there is a catastrophic weather event in Atlanta, the two-hour drive from Birmingham or the 90-minute drive from Chattanooga isn't worth the hassle. You’ll almost always pay more for the flight and the gas than you’d save on the ticket. ATL is a machine; even when it’s crowded, it’s efficient.
Actionable Steps for Your Trip
To make this easy, here is exactly how you should handle your booking process:
- Fly into ATL, not MGE. Don't let the military base code fool you.
- Track prices for mid-week travel. Tuesdays and Wednesdays are almost always $40-$60 cheaper than Sunday afternoon flights.
- Download the FlyDelta app or the MARTA On the Go app. Even if you aren't flying Delta, the ATL airport map in their app is the best one available.
- Check the Braves schedule. If the Atlanta Braves are playing at Truist Park (which is basically Marietta-adjacent), traffic and hotel prices will skyrocket. If you can, fly in when the team is away.
- Book your rental car early. Since Marietta is a suburban hub, the demand for SUVs and mid-sized cars at the airport is relentless.
If you stick to the major carriers and avoid the 5:00 PM traffic window, getting to Marietta is actually one of the easier travel hauls in the South. Just keep your eyes on the "Northbound I-75" signs and keep some extra change for the tolls.
