If you’re flying Delta in or out of Atlanta, Georgia, you’re using Delta’s main hub at Hartsfield-Jackson Atlanta International Airport (ATL). But ATL is big and can be confusing, especially when you’re not sure which terminal or concourse you need.
Here’s the short answer:

| Type of Flight | Check-In Terminal | Likely Concourse(s) | Notes |
|---|---|---|---|
| Delta domestic (within the U.S.) | Domestic Terminal – South (Delta) | T, A, B, C, D | Most Atlanta-area Delta flyers will use this side |
| Delta international departure | International Terminal | E, F | Check your ticket; many long-haul Delta flights use Concourse F |
| Delta international arrival | N/A (you’re landing) | E, F | Go through customs at the International Terminal side |
| Delta domestic connection only | Already in secure area | T–D mostly, sometimes E/F | Use the Plane Train to move between concourses |
This avoids riding the airport shuttle across the property after you arrive.
Both sides of ATL have parking options, but for simplicity:
