Frontier at Atlanta Airport: Terminal, Gates, Check-In, and How to Get There

If you’re flying Frontier Airlines from Atlanta, everything you’ll do—check-in, security, boarding, and baggage claim—happens in the Domestic Terminal at Hartsfield-Jackson Atlanta International Airport (ATL).

Below is a clear breakdown of where Frontier is in Atlanta Airport, how to get to the right check-in area, which concourse to expect, and how to move around once you’re inside.

Where Frontier Is Located at Atlanta Airport

At ATL, Frontier Airlines operates from the Domestic side of the airport, not the International Terminal.

Frontier Airlines – Key Location Info at ATL

Frontier does not have its own separate building; it shares ATL’s large Domestic Terminal with several other airlines.

Step-by-Step: How to Find Frontier in Atlanta Airport

1. Arriving at the Right Terminal

Hartsfield-Jackson has:

• Domestic Terminal (North & South) – for most U.S. flights
• Maynard H. Jackson Jr. International Terminal (Concourse F) – for many international arrivals and departures

Frontier uses the Domestic Terminal.

Look for road signs or MARTA directions labeled “Domestic Terminal”. Once there, you’ll want the South side of the building.

If You’re Driving or Getting Dropped Off

Use this address for navigation:

From there, follow signs for:

• “South Terminal” or “South Terminal – Departures”
• Frontier’s logo/airline list on overhead signs near drop-off

Most rideshares and taxis will ask if you’re going to North or South. For Frontier, say “South Terminal, Domestic”.

If You’re Taking MARTA

1. Take MARTA’s Red or Gold Line to Airport Station (the last stop on both lines).
2. The station exits directly into the Domestic Terminal.
3. When you come up the escalator/elevator from MARTA, you’ll be in the central atrium. Follow signs pointing to “South Terminal / South Ticketing”.
4. From the atrium, walk a few minutes toward the South side to reach Frontier’s check-in counters.

Frontier Check-In and Ticket Counter at ATL

Frontier’s check-in counters are located in the Domestic Terminal – South ticketing hall.

Once you’re inside the South side:

• Look for Frontier’s green and white branding above the counter area.
• Self-service kiosks may be available near the counters for printing boarding passes and bag tags.
• For checked bags or in-person assistance, you’ll use the staffed ticket counters.

🕒 Timing tip for Atlanta travelers:
ATL is one of the busiest airports in the world, and security lines can be unpredictable. Many travelers flying Frontier from Atlanta aim to arrive:

• At least 2 hours before a domestic flight
• Earlier during peak morning and evening periods, holidays, or major events in the city

Always confirm recommended check-in times on your booking details.

Security: Getting from Frontier Check-In to the Gates

After checking in with Frontier at the South Terminal, follow signs to “Security”. You’ll enter the main Domestic security checkpoints.

Once you clear security:

• You’ll be in the Concourse T area or in the central domestic connector.
• From there, you can walk or take the Plane Train (underground people mover) to other concourses (A, B, C, D, E, F).

Frontier flights commonly use gates in Concourse T or D, but gate assignments can change. Always rely on:

• Your boarding pass
• The overhead flight information displays inside the terminal

Frontier Gates and Boarding Areas in Atlanta

Frontier does not have an exclusive concourse at ATL. Instead, it uses gates in the domestic concourse system, usually:

• Concourse T (closest to the main terminal)
• Concourse D (a short Plane Train ride away)

Getting to the Right Concourse

Once you’re past security:

• For Concourse T:
  • Often walkable directly from the security exit; follow overhead signs to “T Gates.”
• For Concourse D:
  • Follow signs to the Plane Train.
  • Ride the train to “Concourse D” (announced clearly on board).
  • Exit and follow signs up to the gate area.

Plan for a few extra minutes of walking and waiting for the Plane Train, especially if you’re not familiar with ATL’s layout.

Baggage Claim for Frontier in Atlanta

When you land in Atlanta on a Frontier flight:

• You’ll arrive at a domestic concourse (likely T or D).
• Follow signs to “Baggage Claim / Ground Transportation”.
• Take the Plane Train (or walk) back toward the Domestic Terminal and then follow signs for the South-side baggage claim.

Frontier’s baggage will be assigned to specific carousels in the Domestic baggage claim area near the South Terminal. Check the overhead monitors for your flight number and carousel assignment.

Once you’ve collected your bags, you can exit to:

• Ground transportation (rideshare, taxis, hotel shuttles)
• MARTA Station (for rail service into Downtown, Midtown, Buckhead, North Springs, etc.)

Getting Around the Airport Once You’re Inside

ATL is large, but it’s laid out in a straight line, which makes navigation fairly straightforward.

Key Ways to Move Between Frontier Areas

• Walking:
  • You can walk between most nearby concourses via underground corridors. It’s well-marked but can be a long walk if you’re short on time.
• Plane Train (People Mover):
  • The quickest option for most travelers.
  • Runs between all concourses (T, A, B, C, D, E, F) and the Domestic Terminal.
  • Trains arrive frequently and are easy to follow with signs and audio announcements.
• Shuttles:
  • For parking lots, car rental center, and some off-airport services, use dedicated shuttles from the ground transportation area.

Frontier and the International Terminal at ATL

If you see tickets or itineraries that mention Concourse F or the Maynard H. Jackson Jr. International Terminal, keep this in mind:

• Most Frontier flights from Atlanta are domestic, operating from the Domestic Terminal side.
• Connecting international flights on other airlines may use Concourses E or F, but your Frontier departure/arrival from Atlanta will still use the Domestic Terminal.

If you accidentally get dropped off at the International Terminal:

• You can take the free airport shuttle between the International Terminal and the Domestic Terminal.
• Follow signs for “Domestic Terminal Shuttle” and allow extra time to make your flight.

Helpful Local Tips for Atlanta Travelers Flying Frontier

• Traffic planning: Atlanta traffic on I-75, I-85, and I-285 around the airport can be heavy, especially weekday mornings and late afternoons. Add buffer time if you’re driving from Midtown, Buckhead, or the northern suburbs.
• MARTA advantage: From Downtown or Midtown, MARTA’s Airport Station is often the most reliable way to avoid traffic when catching a Frontier flight.
• Late-night arrivals: If you arrive late on Frontier, some dining and shops in the concourses may be closed. Plan ahead for snacks, especially if you still have a drive into the city.
• Check your gate often: Gate changes are common at ATL. Use the airport monitors or airline app to double-check your Frontier gate before and after you eat or shop.
