Delta has operated all Boeing 767 models: -200, -300/300ER and -400ER, and currently flies the world's largest 767 airline fleet.

In 1982, Delta's first 767-200 aircraft offered:

• Wide-body convenience & comfort.
• New advanced wing design, which allowed more efficient lift for quicker climb to cruising altitude.
• Quieter and 30 percent more fuel-efficient than Delta's older jets it replaced.
• Digital "glass cockpit" that included 40 computers.
• Flight deck design similar to the  Boeing 757, so the FAA allowed pilots who flew the 767 to also fly the 757 without going through additional training. Delta, the first carrier to fly both 757 and 767, made commercial aviation history in 1984, when two of its pilots completed a demonstration of common-type pilot rating.

Delta Ship 102 holds a special place in Delta hearts and history. Employees purchased Delta's first 767 as a gift to the airline and named it "The Spirit of Delta"; now on display at the Delta Museum.  Learn more.

Delta was the first U.S. carrier to fly a Boeing 767-300 in scheduled service on December 1, 1986. Inaugural flight: Atlanta-Miami, Florida.

The -300 was a stretched version of the -200 model. Carrying 60 more passengers, its fuselage was longer by 21 feet and 3 inches. It was 20 percent more fuel efficient and carried 25 percent more cargo than the 767-200.

Delta purchased the -300 for "intermediate and long-range runs that enjoy heavy demand." Initial service from New England, New York and Montreal, Canada, to Florida and the Bahamas. In the 1990s, the 767-300 frequently flew Delta's transcontinental and Hawaiian routes. By 2006, it was flying for Delta in Latin America, Puerto Rico and on the U.S. mainland between Atlanta and Florida and over medium to long transcontinental routes.

Delta was launch customer for this final extended-range version of the 767 in 1997, continuing plans to retire its international  L-1011s. The -400ER model stretched 21.1 feet to 201.4 feet with a wingspan increase of 14.3 feet to meet the need for a Boeing airliner sized between the -300 model and  777-200. The -400ER also featured improved electrical and air-conditioning systems, increased takeoff weight, "raked" wingtips to increase fuel efficiency, and a new 777-style interior.

Delta took delivery of its first 767-400ER on August 11, 2000, and began replacing  L-1011s on high-volume domestic flights:

• First Delta 767-432ER service: Oct. 1, 2000, between Atlanta and the Florida cities of Orlando, Miami, Fort Lauderdale and Tampa.
• By the end of 2000, to San Francisco, Los Angeles, Honolulu, Maui and Salt Lake City.
• By April 2001, to New York-LaGuardia and San Juan, Puerto Rico.

Delta received its 100th 767 jet from Boeing on October 23, 2000. It was the sixth 767-400ER delivered to Delta in 2000.

On March 27, 2007, Delta announced plans to convert its entire 767-400ER fleet to an international configuration, featuring a BusinessElite cabin. Lie-flat seats were installed in the -400ER BusinessElite cabins in Spring 2009.

At the end of 2009, Delta 767-432ERs international destination included Buenos Aires, Argentina; Caracas, Venezuela; Lima, Peru; London and Manchester, England; Madrid, Spain; Munich, Germany; Rio de Janeiro and Sao Paulo, Brazil; Milan and Rome, Italy; and Tel Aviv, Israel. The 767-432ER also continued to fly high-volume domestic flights.
