Where to Find Delta at ATL: Terminals & Concourses

ATL has two main landside terminals (where you check in) and seven airside concourses (T, A–F), plus an international terminal entrance:

• Domestic Terminal – North and South
• International Terminal – Maynard H. Jackson Jr. Terminal (Concourse F entrance)

Delta primarily uses:

Check-In & Departure Areas

• Domestic flights:

  • Terminal South – Delta is the main area for domestic Delta check-in and baggage drop.
  • If you’re local and flying within the U.S., you’ll typically go to Domestic Terminal South.

• International flights:

  • Many Delta international departures use the International Terminal (Concourse F entrance).
  • Some international flights may depart from other concourses (like E), but tickets and your booking will clearly indicate check-in location.

Gates & Concourses for Delta Flights

Delta has a large presence in these concourses:

• Concourse T – Mix of domestic flights; multiple Delta gates
• Concourse A – Heavily used by Delta for domestic routes
• Concourse B – Another major Delta domestic concourse
• Concourse C – Used by Delta and its partners for domestic/regional service
• Concourse D – Mix of carriers; some Delta operations
• Concourse E – International flights (Delta and other airlines)
• Concourse F – Maynard H. Jackson Jr. International Terminal, major Delta international hub area

All concourses are connected airside by the Plane Train (underground airport train) and pedestrian walkways, so you can move between them without exiting security.

Getting to Delta at ATL: Ground Transportation for Atlanta Locals & Visitors

MARTA (Atlanta’s Rail System)

For many Atlanta residents and visitors, MARTA is a convenient way to reach Delta flights:

• Airport Station is located inside the Domestic Terminal, near baggage claim.
• If you’re flying Delta domestically, taking MARTA directly to the Domestic Terminal is usually easiest.
• If your flight leaves from the International Terminal (F), there is a free international shuttle connecting Domestic and International terminals.

Driving, Parking & Drop-Off

If you’re driving:

• Domestic Terminal South: Follow signs for “Delta” or “South Terminal”.
• Curbside drop-off is available for quick passenger unloading.
• Multiple parking options:
  • Hourly Parking (closest, more expensive)
  • Daily Parking
  • Economy or Park-Ride lots

If you’re headed to the International Terminal (F) for a Delta international flight, follow highway signs specifically for the International Terminal rather than the Domestic side to avoid backtracking.

Delta Check-In, Security, and Boarding in Atlanta

Check-In Options

For Delta flights out of Atlanta, you can typically use:

• Online / mobile app check-in (often opens 24 hours before departure)
• Self-service kiosks in the terminal for boarding passes and baggage tags
• Full-service check-in counters for special assistance, complex trips, or when traveling with certain items (like pets or oversized baggage)

Local tip: Morning departures (6–9 a.m.) are some of the busiest times for Delta at ATL. Allow extra time for check-in and security during these windows, especially on Mondays and at the start of holidays.

Security Screening

You’ll go through TSA security after check-in:

• Regular lanes for standard screening

• Some Delta flyers with certain status or ticket types may have access to priority security lanes in busy periods.

After security, you’ll hop on the Plane Train or use walkways to reach your specific concourse and gate.

Boarding

Delta typically boards by group/zone, which is indicated on your boarding pass. At ATL, announcements may be frequent due to the volume of flights, so:

Delta for Atlanta Residents: Everyday Travel Considerations

Using Atlanta as Your Home Airport

If you live in Atlanta and frequently fly Delta:

• Nonstop options can be a major advantage for both work and leisure trips.
• You might find it easier to maintain frequent flyer status, since many routes route naturally through ATL.
• Early-morning and late-evening flight options can offer flexibility, but they may also be popular with business travelers.

Planning Your Airport Timing

Because ATL is extremely busy and Delta operates many flights close together:

• Build in extra time if you’re checking bags or traveling at peak times
• If you’re only carrying a bag and using mobile boarding, you may move more quickly through the airport
• For holidays and large events in Atlanta (major conventions, sporting events, etc.), anticipate longer lines at Delta counters and security

Delta Connections in Atlanta: What to Expect for Layovers

Many travelers just connect through Atlanta on Delta without leaving the airport. If that’s you:

Typical Connection Process

1. Arrive at a Delta gate in one concourse
2. Check departure boards for your next Delta flight’s gate and concourse
3. Take the Plane Train to your new concourse (if needed)
4. Proceed directly to the next gate if you already have your boarding pass

For domestic-to-domestic connections on Delta within ATL, you usually do not need to go through security again as long as you remain airside.

International Connections

For connections involving international flights:

• On arrival to Atlanta from abroad, you normally go through U.S. Customs and Border Protection, pick up checked bags, and then recheck them before continuing, depending on current procedures and your final destination.
• If Atlanta is your final stop, you’ll exit into the International Terminal and can use ground transportation from there.

Getting Help From Delta in Atlanta

If you need help while at ATL:

• Delta check-in counters in the Domestic and International terminals can assist with reservations, check-in, and baggage issues during operating hours.
• Customer service desks near Delta gates can help with same-day flight changes, rebooking during delays, and basic questions.
• For lost baggage, Delta has baggage service offices inside ATL where you can file or follow up on a report.

For more complex situations (repeated disruptions, schedule changes, or ticket questions before you come to the airport), many travelers prefer to use:

• The Delta mobile app
• Phone-based customer support

If you are in Atlanta and your travel plans change unexpectedly, heading to Delta’s staffed counters at ATL can sometimes help you get same-day answers and adjustments.
