Overview
Delta Air Lines, Inc. is a U.S.-based airline whose core business is transporting passengers through a domestic and international flight network. It also carries cargo on scheduled passenger flights. Delta describes its purpose in terms of connecting customers across its network and making travel more connected, personalized and enjoyable.[1][2]
Delta’s operations span six continents, with flights to more than 300 destinations at year-end 2025; together with its alliance partners, its network reached more than 150 countries and territories. The company also operates a refinery that supplies fuel to its airline business. In 2025, Delta reported $63.4 billion in operating revenue and employed approximately 103,000 full-time-equivalent people.[3][4][5][6] [1][2][3][4][7][6][5]
Products & services
Delta sells passenger air travel across Main Cabin and four named premium products: Delta Comfort+, First Class, Delta Premium Select and Delta One. The premium products offer different seating and service levels, from extra-legroom seating to premium long-haul cabins. Delta also provides onboard entertainment and connectivity, and operates Delta Sky Clubs and Delta One Lounges for eligible travelers.[8][9][10][11]
SkyMiles members can earn miles through Delta and participating partners and redeem them for flights, upgrades and other awards. Beyond passenger tickets, Delta offers vacation packages, air-cargo transport using space on scheduled passenger flights, and third-party aircraft maintenance, repair and overhaul services through Delta TechOps. Passenger services are the dominant revenue source: they accounted for approximately 82% of total operating revenue in 2025, compared with about 1% for cargo and 17% for other revenue.[12][13][2][14] [8][9][12][13][2][14][10][11]
Geographic presence
Delta Air Lines is based in Atlanta, Georgia, with most of its principal offices at or near the Atlanta airport. Its U.S. network is centered on hubs in Atlanta, Detroit, Minneapolis–St. Paul and Salt Lake City, with coastal hubs in Boston, Los Angeles, New York–LaGuardia, New York–JFK and Seattle. Internationally, it identifies Amsterdam, Bogotá, Lima, London–Heathrow, Mexico City, Paris–Charles de Gaulle, Santiago, São Paulo, Seoul–Incheon and Tokyo as locations where it has significant hubs or a presence in key markets. At the end of 2025, Delta offered up to 5,500 flights on peak days to more than 300 destinations across six continents.[15][16][17][18][3]
In 2025, domestic markets accounted for $44.7 billion, or approximately 70.5%, of Delta’s $63.4 billion in operating revenue. The Atlantic region contributed $10.8 billion (17.0%), Latin America $4.6 billion (7.2%) and the Pacific region $3.4 billion (5.3%). Delta assigns airline revenue to geographic regions based on flight segments’ origins, paths and destinations, rather than solely on the customer’s location.[19] [15][16][17][18][3][19][19][19][19][19]
Business segments
Delta Air Lines reports two operating segments: Airline and Refinery. Airline is an integrated business providing scheduled passenger and cargo air transportation, together with loyalty and ancillary businesses. Refinery comprises Monroe Energy’s fuel operations, which supply jet fuel to the airline and exchange or sell other refined products for jet fuel.[20][21][22]
In 2025, Airline generated $58.3 billion in operating revenue, equivalent to about 92% of consolidated revenue, while Refinery generated $7.0 billion, or about 11%. A negative $1.9 billion intersegment sales and other reconciliation, approximately 3% of consolidated revenue, brings the two segment figures to the consolidated total of $63.4 billion; the segment percentages therefore should not be added without that adjustment. Separately from its operating segments, Delta reports revenue by type: passenger revenue accounted for about 82% of the consolidated total, cargo about 1%, and other revenue about 17%.[7][14] [20][21][22][7][7][7][7][14][14][14]
Company history
Delta Air Lines traces its origins to Huff Daland Dusters, a crop-dusting company founded in 1925. Collett E. Woolman and associates acquired the business in 1928 and renamed it Delta Air Service. Delta began scheduled passenger flights in 1929 and moved its headquarters from Monroe, Louisiana, to Atlanta in 1941.[23]
A series of combinations expanded the airline: Delta merged with Chicago & Southern Air Lines in 1953, Northeast Airlines in 1972 and Western Airlines in 1987. It acquired Pan Am’s transatlantic routes and other assets in 1991.[23] Delta filed for Chapter 11 bankruptcy protection in 2005 and emerged in 2007.[23] Its merger with Northwest Airlines closed on October 29, 2008; Northwest Airlines was subsequently merged into Delta at the end of 2009.[24] [24][23]
