Delta's first 747 (N9896, Ship 101) delivered to Atlanta on October 2, 1970, piloted by Capt. T. P. "Pre" Ball, Delta vice president - flight operations. Four more 747s delivered to Delta by November 1971.

At special dedication ceremonies on October 24, 1970, in Atlanta, Georgia Governor Lester G. Maddox christened Delta Ship 101 "Georgia Belle," sprinkling gold dust over the plane's nose from Georgia's Dahlonega mines. Recalling that Dahlonega, a city in the north Georgia mountains, was site of America's first gold rush, Maddox added, "All the gold mined in Dahlonega could never total in value the amount of goodwill this airplane can deliver."

Following day, October 25, Georgia Belle went into service with one daily roundtrip from Atlanta-Dallas-Los Angeles. Delta used its 747 fleet between the major cities of its route system including: Atlanta, Chicago, Dallas/Ft. Worth, Detroit, Los Angeles, Miami, New York and San Francisco.

Delta 747s were also used on the Delta/Pan Am European interchange, flying from Atlanta and Washington, DC-Dulles over Pan Am's transatlantic routes on April 25, 1971. Delta's employee magazine reported that Ship 105 "caused something of a sensation when it first appeared in London and Frankfurt, on the Delta-Pan American Interchange…the first Delta 747 ever seen in Europe."

Thirty years later, a merger with Northwest Airlines in 2008 brought the 747 back to the Delta fleet: 16 Model 400's, 2 Model 200's and 12 Model 200 freighters.

• 65 BusinessElite seats and 338 economy class seats for a total capacity of 403.
• Ship 6305 was first Northwest 747-400 repainted in Delta livery.
• Ship 6301 was the first 747-400 built by Boeing. 

• 2 Boeing 747-251B passenger planes remained in Northwest's fleet at time of merger with Delta. Used only for charter service. Northwest had retired its last 747-200 from scheduled passenger service on September 12, 2007—the end of transpacific service for 747-200's worldwide. 
• Final charter service: military charter flights on November 25, 2009 (aircraft N623US) and November 27 (aircraft N624US). This was final 747-200 passenger service in U.S.
• 747-200 dedicated cargo fleet that Delta inherited from Northwest flew final freighter flights to Chicago (from Osaka) and Los Angeles (from Shanghai) on December 19, 2009.

Delta retired its 747 fleet for the second and final time in 2017, replacing the 747-400 with more compact and efficient, twin-engine aircraft, such as the Airbus 350. The drawdown began on September 30, 2014, when three of the 16 Boeing 747-400s inherited from Northwest Airlines retired.

The first Boeing 747-400 ever built—Ship 6301—retired from service on September 9, 2015, after logging more than 61 million miles. You can now tour it as the 747 Experience at the Delta Flight Museum.

Delta's last scheduled domestic 747 flight was intended to be an overnight flight with Ship 6309 (N669US) leaving Los Angeles for Detroit on September 5, 2017. However, with Hurricane Irma bearing down on Florida, Delta added new flights ahead of the storm to assist evacuating passengers, including several roundtrip 747 flights between Detroit and Orlando on September 8 and 9, 2017.

In December 2017, Delta became the last U.S. airline to retire the Boeing 747, ending 47 years of service by Northwest Airlines and Delta combined. 

• Last U.S. departure, DL159A, left Detroit on December 18, arriving at Seoul-Incheon on December 19. It was a recovery flight for the original Dec. 17 flight (DL159), cancelled due to lack of pilot staffing. The unique DL159A flight number was assigned to the delayed 747 flight departing on Dec. 18 as there was already an Airbus A350 scheduled to fly as DL159 later that day.
• Final scheduled revenue flight, DL158, left Seoul-Incheon on December 19, 2017, arriving in Detroit on December 19.  
• Ship 6306 (N666US) flew both final revenue flights. It was the ninth 747-400 built, and the oldest one flying in the world. Ship 6306 first flew on July 31, 1989, and was delivered to Northwest on August 18, 1989. 

Delta also took a 747-400 (N674US, Ship 6314) on an employee farewell tour: Detroit to Seattle on December 18, with a special stop at Everett's Paine Field, home of Boeing's final assembly production line that produced the 747 fleet; Seattle to Atlanta on December 19; and Atlanta to Minneapolis-St. Paul on December 20. 

In its final days with Delta, the 747 flew charter flights, carrying NFL and college football teams to championship games. Between December 22, 2017 and January 2, 2018, the 747 visited the following airports: ATL, BUF, DFW, DTW, EWR, FLL, GSP, LAX, MSY, SAN and SEA. Ship 6306 and Ship 6310 (N670US) were withdrawn from service on December 26, leaving Ship 6314 as the final 747 in Delta's fleet.
