Delta uses both buildings. U.S. airlines that list a terminal name the Domestic Terminal. Published November 15, 2026 ![The timber front panels of a check-in counter in the International Terminal's departures hall at Atlanta airport, with the window wall soft behind.](https://atlairportguide.com/images/atl/intl-departures-checkin-counters-v11.webp) A timber-fronted check-in counter, International Departures Every foreign airline at ATL checks in at International Departures in the International Terminal. Delta is the one airline ATL’s directory lists at both buildings, and every other U.S. airline that lists a check-in terminal lists the Domestic Terminal. ## Foreign airlines: International Terminal, International Departures ATL’s airline list calls them the foreign-flag international carriers and gives these numbers. | Airline | Number on ATL’s list | | --- | --- | | Aeromexico | (800) 237-6639 | | Air Canada | (888) 247-2262 | | Air France | (800) 237-2747 | | British Airways | (800) 247-9297 | | Copa Airlines | (800) 359-2672 | | Ethiopian Airlines | (800) 445-2733 | | Etihad | (914) 303-8393 | | KLM | (800) 618-0104 | | Korean Air | (800) 438-5000 | | LATAM Airlines | (866) 435-9526 | | Lufthansa | (800) 645-3880 | | Qatar Airways | (877) 777-2827 | | Scandinavian Airlines | (800) 221-2350 | | Turkish Airlines | (800) 874-8875 | | Virgin Atlantic | (877) 359-8474 | | WestJet | (888) 937-8538 | ## Delta checks in at both buildings [Delta](https://atlairportguide.com/airlines/delta/) has check-in desks at the Domestic Terminal, with curbside check-in there too, and at International Departures in the International Terminal. ATL’s airline list places Delta with the domestic carriers. ATL’s maps page sends passengers flying outside the United States to the International Terminal, which points an international Delta ticket there. To confirm which building yours uses, call Delta on the (800) 221-1212 that ATL’s airline list gives. ## International flight on another U.S. airline ATL’s directory lists the Domestic Terminal alone for American, United, JetBlue, Alaska, Southwest, Frontier and Denver Air Connection. ATL’s maps page and MARTA’s airport page both cover an international ticket on one of them. - ATL’s maps page says passengers traveling outside the United States should check in at the International Terminal, and it tells you to contact your airline for specific check-in requirements. - MARTA’s airport page says it depends on your airline. If yours checks you in for the international flight at the Domestic Terminal, you ride the Plane Train to Concourse F. If it doesn’t, you take the free shuttle outside Baggage Claim. Neither page names which airlines do which, so ask your airline before you leave. ATL’s list also carries Southern Airways Express among the domestic carriers with no check-in terminal given, so ask that airline directly. ## Which concourse your flight uses ATL’s airline list gives phone numbers and websites, not concourses, so your gate comes from your flight. ATL’s flight search finds a flight by carrier and number, such as DL1234, and ATL says to confirm the gate with your airline. A few airlines on this page do have a concourse we can name. [Frontier](https://atlairportguide.com/airlines/frontier/) and [Alaska](https://atlairportguide.com/airlines/alaska/) fly from Concourse E, [Southwest](https://atlairportguide.com/airlines/southwest/) from Concourse C, [Denver Air Connection](https://atlairportguide.com/airlines/denver-air-connection/) from Concourse T and [Etihad](https://atlairportguide.com/airlines/etihad-airlines/) from Concourse F. Denver Air Connection’s ticket counter is in the Domestic Terminal North, between Southwest and Alaska. For every other airline here there’s no concourse to give you, so read the gate off the flight screens. Gates inside a concourse change, so treat the concourse as where to start looking. For arrivals, ATL’s FAQ says international flights arrive at Concourses E and F. Our [concourse map](https://atlairportguide.com/terminals/terminal/) shows where E and F sit. Our [flights page](https://atlairportguide.com/flights/) links each airline’s page with its check-in counters. ## If you reach the wrong building The International Terminal is a separate building and isn’t walkable from the Domestic Terminal. The free [International Terminal shuttle](https://atlairportguide.com/transport/international-terminal-shuttle/) runs between them about every 15 minutes, and MARTA’s airport page says it operates 24/7 with 15 minutes of travel time between them. ATL’s maps page says shuttles leave from the curb outside the International Terminal and drop passengers at the west end of the Domestic Terminal. In the other direction, MARTA’s page puts the shuttle outside Baggage Claim at the Domestic Terminal. ## Sources - Our airlines pages, concourse map and International Terminal shuttle page - ATL’s passenger airlines list, for the foreign-flag carriers and the numbers - ATL’s maps page and FAQ, for the check-in rule, the shuttle’s drop-off point and the arrival concourses - ATL’s ground transportation page, for how often the shuttle runs - ATL’s flight search page, for flight lookups and the gate advice - MARTA’s airport page, for the airline-by-airline check-in rule and the shuttle’s ride time and hours
