About Delta Air Lines

Delta Air Lines is based in Atlanta and is a founding member of SkyTeam. Other hubs include Detroit, Minneapolis/St. Paul, Salt Lake City, New York, Boston, Los Angeles and Seattle, with Delta Connection regional partners feeding smaller cities. It flies throughout the United States and to Canada, Latin America, the Caribbean, Europe, Africa and Asia Pacific, and it works closely with Air France, KLM, Virgin Atlantic, Korean Air and LATAM on joint routes. Long-haul aircraft carry Delta One business class, Delta Premium Select, Comfort and Main Cabin seating, while domestic flights have a first class cabin.

Travel agents can book Delta through the IATA.co portal, and developers can pull the same live results through the flights API. Payment comes from a prepaid balance that you top up in advance. Delta Air Lines fares appear in your search results whenever our flight suppliers offer them for your route and dates. IATA.co is an independent booking platform, so availability depends on those suppliers and not on any direct arrangement with the airline.

Delta Air Lines is a full-service carrier, based in United States, operating mainly from Atlanta (ATL). It is a member of SkyTeam.

Booking Delta Air Lines fares as a travel agent

Travel agents book Delta Air Lines fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live DL fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. Delta Air Lines results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.

Search Delta Air Lines (DL) through the flights API

Developers and agencies can run the same Delta Air Lines search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code DL and read the fares back as JSON, then book from the same prepaid balance. See the flights API and the API docs for the full reference.
