• PDK – DeKalb–Peachtree Airport (general aviation, northeast of downtown)

The airport you know as ATL actually has several identifiers:

• IATA code:ATL
  • Used by airlines, booking sites, and passengers
• ICAO code:KATL
  • Used by air traffic control and pilots
• FAA code:ATL
  • Used by the Federal Aviation Administration in the U.S.

For everyday travelers in or to Atlanta, ATL is the only code you typically need to remember.

Terminals and Concourse References at ATL

While ATL is a single airport code, once you’re inside, you’ll see a lot of letter-based concourse designations. These aren’t separate airport codes, but it’s helpful to understand them:

• Domestic Terminal – North and South
• International Terminal – Maynard H. Jackson Jr. Terminal (Concourse F)
• Concourses: T, A, B, C, D, E, F

On your boarding pass, you might see something like:

• ATL – Concourse B – Gate B12
• ATL – International Terminal – Gate F5

That still means Atlanta, GA (ATL), just specifying where you need to go within the airport.

Quick Reference: Atlanta-Area Airport Codes

Here’s a simple overview of airport codes that matter most to people in and around Atlanta:

For normal airline travel to or from Atlanta, you will almost always book flights to/from ATL.

Using ATL When You Book Travel

When you’re booking flights and the system asks for an airport or city:

• Typing “Atlanta” will usually show:
  • Atlanta, GA (ATL – Hartsfield–Jackson)
• You can also directly type “ATL” to avoid confusion with other cities named Atlanta.

✅ Tip for locals:
If you have out-of-town friends or family visiting, remind them to double-check that their ticket says ATL and specifically says “Atlanta, GA” as the airport location.

Getting To and From ATL in Atlanta

Once you know the airport code ATL, the next question is usually: “How do I get there from where I am in Atlanta?”

MARTA (Rail and Bus)

MARTA is one of the easiest ways to reach ATL from many parts of the city:

• Airport Station is located inside the Domestic Terminal (at the end of the Red and Gold rail lines).
• From Downtown, Midtown, or Buckhead, you can usually reach ATL in about 20–30 minutes by train.
• For travelers arriving at the International Terminal (Concourse F), a free shuttle connects you to the MARTA Airport Station at the Domestic Terminal.

If you’re staying near a MARTA rail station, entering ATL as your destination for mapping will usually default to the airport’s rail stop or terminal address.

Driving and Rideshare

When entering directions in a GPS or map app, use:

• “Hartsfield–Jackson Atlanta International Airport”
• Or the address: 6000 N Terminal Parkway, Atlanta, GA 30320

Rideshare drivers will almost always know “ATL” or “Atlanta airport” as a destination, but specifying Domestic vs. International Terminal is important.

Domestic vs. International at ATL

Although the airport code remains ATL, the experience differs depending on whether you’re flying within the U.S. or to/from another country.

Domestic Flights

• Use the Domestic Terminal (North or South)
• Airline check-in counters are divided between the North and South sides
• Gates are in Concourses T, A, B, C, and D (and sometimes E)

International Flights

• International departures and arrivals primarily use:
  • International Terminal (Concourse F)
  • Some international arrivals/departures also use Concourse E
• Your boarding pass will list ATL as the airport code even if you’re flying to/from cities abroad; what changes is the concourse and gate.

Other Atlanta-Area Airports You Might See

Even though ATL is the main passenger hub, you might come across other airport codes if you’re dealing with private flights, charters, or local aviation.

Fulton County Airport – Brown Field (FTY)

• Code:FTY
• Location: West of downtown Atlanta, near I-20
• Use: Primarily general aviation, corporate flights, charters, flight training

While travelers booking regular airline tickets typically won’t use FTY, locals sometimes see this code:

• On aviation services
• On smaller charter itineraries
• In weather reports or flight tracking apps

DeKalb–Peachtree Airport (PDK)

• Code:PDK
• Location: Chamblee, just northeast of Atlanta proper
• Use: General aviation, corporate and private jets, some charter operations

People who live in Brookhaven, Chamblee, or Dunwoody may be very familiar with PDK, especially due to lower-flying aircraft overhead, but it is not Atlanta’s main commercial airport.

Common Questions About the Atlanta Airport Code

Is there more than one commercial airport code for Atlanta?

For typical airline passengers, no.
ATL is the primary commercial airport code for the Atlanta metropolitan area.

Codes like FTY and PDK refer to secondary, mostly general-aviation airports and are not used for major airline service to the city.

What if my ticket shows KATL instead of ATL?

Most standard passenger tickets will show ATL, but if you see KATL, that’s the ICAO code used for aviation operations. It still refers to the same Atlanta airport.

Are there other cities named Atlanta with different codes?

Yes. There are smaller towns named Atlanta in other states with their own airport codes (for small local airports).
If you are traveling to Atlanta, Georgia, make sure your ticket clearly lists ATL – Atlanta, GA.

Practical Tips for People Traveling Through ATL

• Verify your code: Always double-check that your itinerary shows ATL for Atlanta, Georgia.
• Check the concourse: At ATL, your gate/concourse (T, A, B, C, D, E, F) matters as much as the airport code, due to the airport’s size.
• Plan transfer time: If you’re connecting at ATL, allow enough time to move between concourses using the Plane Train or the pedestrian walkway.
• Clarify terminal in pickups: When arranging rides or pickups, specify:
  • “ATL Domestic Terminal, North/South” or
  • “ATL International Terminal (Concourse F)”

Remember: whether you’re a local, a frequent visitor, or flying through for the first time, ATL is the code you need to know for Atlanta’s main airport.
