How travel agents book Delta Air Lines

GDS distribution

Delta content is distributed through the GDSs. In September 2024 Travelport signed a multi-year renewal with Delta that includes NDC content, and Delta said its NDC technology would be offered to all Travelport agency customers.

NDC

Delta has an NDC programme and began NDC pilots with corporate buyers and travel management companies in 2018, working with Virgin Atlantic on shared NDC principles. In September 2024 Travelport and Delta began integrating Delta's NDC offers into Travelport+; live availability in other GDSs was not verified.

Direct channels

Direct channels include delta.com and the Fly Delta app. Delta Professional (pro.delta.com) is Delta's business-to-business site for travel agencies and corporate travel managers, with policies and agency news.

Notes for travel agents

Agency policies, including debit memo, refund and exchange rules, are published on Delta Professional; check live NDC status with your GDS before relying on NDC-only offers.

On ReservationHub

Delta Air Lines is one of the direct airline connections listed on our integrations page, alongside GDS (Amadeus, Sabre, Travelport) and NDC content. Agencies get it in the SaaS platform; developers through the Travel API.

History of Delta Air Lines

Delta began in 1925 as Huff Daland Dusters, a crop-dusting company in Macon, Georgia, and took the Delta name in 1928. Its first passenger flight, on 17 June 1929, ran from Dallas, Texas, to Jackson, Mississippi, with stops in Shreveport and Monroe, Louisiana. The company later moved its head office to Atlanta, which became the centre of its network.

Delta grew through mergers with other US airlines, most recently Northwest Airlines in 2008, which added hubs in Detroit and Minneapolis-St Paul and a large Pacific network. In 2000 it was one of the founding members of SkyTeam, along with Aeroméxico, Air France and Korean Air. Its SkyMiles loyalty programme dates from 1981.

Delta has built joint ventures with Air France-KLM, Virgin Atlantic, Korean Air and LATAM, and owns 49% of Virgin Atlantic. In distribution, Delta and Virgin Atlantic worked together on NDC from 2018, and in September 2024 Travelport renewed its agreement with Delta and began integrating Delta's NDC offers into Travelport+.
