Curbside check-in at the Domestic Terminal, Atlanta airport

[Find your airline](https://atlairportguide.com/airlines/): Concourse, check-in counters, bag claim and where to park, for every airline here.

Atlanta is Delta’s hometown airport, and Delta checks you in at both of its terminals. There are desks in the Domestic Terminal and on the International Terminal’s departures level, and ATL lists one curbside desk, at the Domestic Terminal.

## Where the desks and the curbside desk are

ATL’s listing for [Delta Check-in in the Domestic Terminal](https://atlairportguide.com/venues/delta-check-in-domestic-terminal/) gives no side and no hours, so it doesn’t say whether the desks are north or south. The [International Terminal desks](https://atlairportguide.com/venues/delta-check-in-international-terminal/) have no hours listed either. Delta says its desks have a Sky Priority lane. Gold, Platinum and Diamond Medallion members use it, and so do Delta One, Delta Premium Select and Delta First passengers.

ATL lists one [Delta curbside desk](https://atlairportguide.com/venues/delta-curbside-check-in/), at the Domestic Terminal, with no door, level or hours. Delta says its curbside desks sit at passenger drop-off. There’s no fee, though Delta says gratuities are welcome. Oversized bags may have to go inside, where ATL lists oversize baggage screening in the Domestic Terminal and at International Departures. At the International Terminal, go in to the departures level.

## Which terminal for your flight

ATL’s maps page answers by destination. Passengers flying outside the United States check in at the International Terminal, and passengers flying within the United States check in at the Domestic Terminal. It says to contact your airline for specific check-in requirements, and neither ATL’s pages nor Delta’s two check-in pages list Delta flights one by one. If you still can’t tell, call Delta at (800) 221-1212, the number on ATL’s airline list for [Delta](https://atlairportguide.com/airlines/delta/).

The terminals are not walkable from each other. A free shuttle leaves the curb outside the International Terminal for the west end of the Domestic Terminal, and the Plane Train links the two as well. In the other direction, the [terminal shuttle](https://atlairportguide.com/transport/international-terminal-shuttle/) boards outside baggage claim at the Domestic Terminal. [MARTA](https://atlairportguide.com/transport/marta-rail/) ends at the Domestic Terminal, so if you check in at the International Terminal you take the shuttle across.

## How early to check in

You can check in online or in the Fly Delta app up to 24 hours before departure. Delta also offers check-in at an airport kiosk or desk. Delta and ATL both recommend arriving two hours before a domestic flight. ATL also recommends three hours before an international one.

| Domestic flight | Cutoff before departure |
| --- | --- |
| Checking a bag | 45 minutes |
| No checked bag | 30 minutes |
| At the gate, ready to board | 15 minutes |

ATL isn’t one of the airports Delta lists with different minimums, so these apply. Delta won’t accept checked bags more than 6 hours before departure, and it publishes international minimums on a separate page.
