Delta Air Lines: A Century of Aviation History

Delta's history stretches back to 1925, when it began as Huff Daland Dusters, an agricultural crop-dusting company in Macon, Georgia. It evolved into Delta Air Service in 1928 and launched passenger service in 1929 between Dallas and Jackson, Mississippi. Over the following century, Delta grew through strategic acquisitions including Western Airlines (1987), Pan Am's transatlantic routes (1991), and most significantly, Northwest Airlines in 2008 — creating the world's largest airline at the time and cementing Delta's position as a true global carrier.

Today, Delta holds equity stakes in several international airlines including GOL (Brazil), LATAM Airlines, Air France-KLM, Korean Air, and Virgin Atlantic, giving it unparalleled commercial reach across Latin America, Europe, and Asia-Pacific. The airline operates from its massive hub at Hartsfield-Jackson Atlanta International Airport (ATL) — consistently the world's busiest airport by passenger volume — and seven additional domestic hubs.

Delta Air Lines Fleet

Delta operates one of the most modern and environmentally progressive fleets in global aviation. Key aircraft in service include:

• Airbus A220-100 & A220-300 — Delta was the North American launch customer for this next-generation narrowbody; features wider seats, larger windows, lower cabin altitude, and exceptional fuel efficiency for thin domestic routes
• Airbus A319, A320, A321 — the core of Delta's domestic narrowbody fleet, serving hundreds of city pairs across the U.S. and Caribbean
• Boeing 737-800 & 737-900ER — legacy narrowbody workhorses being supplemented by A220s and A321s
• Boeing 757-200 & 757-300 — unique transcontinental capability aircraft, used extensively on premium New York routes
• Boeing 767-300ER & 767-400ER — widebody aircraft used on select transatlantic and Latin American routes; features Delta One flatbed seats
• Airbus A330-300 & A330-900neo — high-capacity widebody used extensively on European and Asian routes
• Airbus A350-900 — Delta's flagship ultra-long-haul aircraft, featuring the stunning Delta One Suite with sliding doors and fully flat beds; used on premium routes including Atlanta–Seoul, Atlanta–Tokyo, and New York–Johannesburg
• Airbus A321XLR — ordered and incoming; will open new thin transatlantic routes impossible for current narrowbodies

Delta One: Award-Winning Business Class

Delta One is consistently ranked among the world's best airline business class products, winning awards from Skytrax, Business Traveler, and Travel + Leisure year after year. On aircraft equipped with the Delta One Suite — notably the A350 and select 767s — passengers enjoy:

• Fully enclosed private suite with sliding door for complete privacy
• Fully flat 180-degree lie-flat bed up to 76 inches in length
• Westin Heavenly in-flight bedding, pillow, and duvet

On aircraft without the Delta One Suite (older 767s, 757s on select transcon routes), Delta One still features flatbed seating, premium dining, and a first-class experience. Call +1 (888) 457-7599 to check Delta One availability and pricing on your specific route.

Delta SkyMiles: Loyalty That Doesn't Expire
