Delta's logo, often called the "widget", was originally unveiled in 1959. Its triangle shape is taken from the Greek letter [[delta (letter)|delta]], and recalls the airline's early history operating in the [[Mississippi Delta]].<ref name="Mouawad1">{{cite news | first=Jad | last=Mouawad | title=On Jet Exteriors, a Parade of Vanilla | url=https://www.nytimes.com/2011/12/24/business/on-the-exterior-of-jetliners-a-parade-of-plain-vanilla.html | work=[[The New York Times]] | date=December 23, 2011 | url-access=subscription | access-date=February 7, 2017 | archive-url=https://web.archive.org/web/20220610053107/http://www.nytimes.com/2011/12/24/business/on-the-exterior-of-jetliners-a-parade-of-plain-vanilla.html?_r=0 | archive-date=June 10, 2022 | url-status=live}}</ref> It is also said to be reminiscent of the swept-wing design of the DC-8, Delta's first jet aircraft.<ref>{{cite web |url= http://www.famouslogos.us/delta-airlines-logo/ |title= Delta Air Lines Logo |access-date= July 15, 2016 |archive-url= https://web.archive.org/web/20170313124416/http://www.famouslogos.us/delta-airlines-logo/ |archive-date= March 13, 2017 }}</ref>

Delta's current [[Aircraft livery|livery]] is called "Upward & Onward". It features a white fuselage with the company's name in blue lettering and a widget on the vertical stabilizer. Delta introduced its current livery in 2007 as part of a re-branding after it emerged from bankruptcy. The new livery consists of four colors, while the old one (called "colors in motion") uses eight. This meant the switch saved the airline money by removing one day from each aircraft's painting cycle. The airline took four years to repaint all of its aircraft into the current scheme, including aircraft inherited from Northwest Airlines.<ref name="Mouawad1"/>
