Huff Daland Dusters, the humble crop dusting operation that grew into the world's most profitable airline, was founded in Macon, GA, in March 1925.
Delta's roots in the American South remain a key part of the airline's hospitality and people-driven culture, the airline's Chief People Officer Allison Ausband told Business Insider in an interview.
"We've never lost sight of where we started," Ausband, whose Delta career began as a flight attendant four decades ago, said.
The airline recently closed the flight museum located at its headquarters on the northern edge of Hartsfield-Jackson Atlanta International Airport for renovations and the installation of new exhibits in celebration of its 100th anniversary.

The museum's main facility is housed in a pair of former maintenance hangars dating back to the 1940s.

The hangars, which total 68,000 square feet of space, date back to 1941 and 1947, respectively. They are among the last remnants of the original Atlanta Municipal Airport.
The entrance to the museum's lobby features columns made from the nose gears of retired airliners.

In 1993, a group of Delta retirees found the plane flying cargo in Puerto Rico and brought it back to Atlanta for restoration. The DC-3's restoration helped spur the creation of the Delta Flight Museum in 1995.
Next to the DC-3 is a Link flight simulator from the 1940s/50s.

Delta employees salvaged the 65-foot-long section in 1989. It has been used as a movie set and gift shop before becoming a conference room.
Besides airplanes, the museum also houses thousands of pieces of aviation memorabilia.

There's also a McDonnell Douglas DC-9 that joined the Delta through its 2008 merger with Northwest Airlines.
