  • Make simple itinerary adjustments

Baggage for Southwest at ATL

Checking Bags

  • After tagging your bags at a kiosk or with an agent, drop them at the Southwest bag drop in the Domestic Terminal North.
  • Plan to arrive earlier than usual during busy Atlanta travel times (holidays, major events, Monday mornings).

General timing guidelines often used by travelers:

  • At least 2 hours before domestic flights
  • Add extra time if:
    • You’re driving in from metro suburbs like Marietta, Lawrenceville, or Fayetteville during rush hour
    • You’re checking multiple bags or traveling with family

When your Southwest flight lands:

  • You’ll arrive at Concourse C
  • Follow signs to Plane Train / Baggage Claim

If someone is picking you up, they’ll use:

  • North or South passenger pickup lanes at the Domestic Terminal
  • Confirm with them whether you’re coming from Domestic (you are, for Southwest) and not the International Terminal.

Getting Through Security for Southwest Flights

Main Security Checkpoints

From the Domestic Terminal:

  • You’ll use the main security checkpoints (North or South)
  • There is no separate Southwest-only checkpoint; all domestic passengers funnel through the main lanes

TSA PreCheck and CLEAR

If you have TSA PreCheck or CLEAR, ATL typically offers:

  • Dedicated PreCheck lanes at the main security area
  • CLEAR lanes that can shorten the ID check step, then you enter the screening line

These options can be especially helpful at ATL, which is known for heavy peak-hour traffic at security.

🕒 Local tip: Early weekday mornings, Sunday evenings, and major event days in Atlanta (big sports games, conventions, holidays) can mean longer lines. If you’re flying Southwest during those times, consider arriving earlier than usual or using PreCheck if you have it.

Finding Southwest Gates in Concourse C

Once past security:

  1. Follow signs to the Plane Train
  2. Ride to Concourse C
  3. Exit and head up the escalators to the gate level

You’ll see Southwest gates clearly marked on monitors. Concourse C has:

  • Food courts and quick-serve spots
  • Newsstands and convenience shops
  • Seating areas with power outlets in many locations

If you prefer to walk, there’s an underground walkway between concourses with moving sidewalks and art displays, but most Southwest passengers use the Plane Train for speed.

Parking and Drop-Off for Southwest at ATL

Parking Options If You’re Driving

  • ATL West Deck / ATL Economy Lots: Often more budget-friendly, connected by shuttles
  • Off-site private lots: Common along Camp Creek Parkway and around the airport area

Local travelers from areas like Smyrna, Decatur, or Jonesboro often compare daily vs. off-site prices, especially for longer trips.

Passenger Drop-Off and Pick-Up

For Southwest:

  • Departures (drop-off): Domestic Terminal upper level

MARTA is often the easiest way for in-town Atlanta travelers to reach Southwest flights:

  • Take MARTA to Airport Station, the final stop on the Red or Gold line
  • The station connects directly into the Domestic Terminal (near the main check-in area)
  • From there, walk to the Domestic North check-in side for Southwest

This works especially well if you’re staying in:

  • Downtown (Five Points, Peachtree Center)
  • Midtown (Midtown Station, Arts Center)
  • Buckhead (Buckhead, Lenox, Lindbergh Center)

Rideshare and Taxi

Uber, Lyft, and taxis serve the Domestic Terminal:

  • Rideshare pickup: Signed areas near the Domestic Terminal (follow the signs after baggage claim)

If you’re staying around popular Atlanta neighborhoods like Old Fourth Ward, West Midtown, Inman Park, or East Atlanta, rideshare can be simpler than driving and parking.

If you’re connecting in Atlanta:

  • Southwest to Southwest: Typically within Concourse C; just walk between gates

  • International connections:
    • If your Southwest flight connects to an international flight operated by another airline, you’ll usually move from Concourse C to the necessary concourse (E, F, or others) via the Plane Train.
    • Returning from an international trip, you’ll use the International Terminal / Concourse F arrivals, go through customs, then transfer to the Domestic side if needed.

Always allow extra connection time at ATL due to the size of the airport and use of the Plane Train.
