Embraer of Brazil created the EMB-120 Brasilia as a successor to it's smaller, unpressurized 19-seat EMB-110 Bandeirante. At the time, most commuter planes with 19-seat props with no pressurized cabins, no flight attendants/galley/inflight service, and no lavatory. Embraer saw an opportunity to produce a comfortable 30-seat turboprop with more comfort and amenities than the competition. The EMB-120 mad it's first flight in 1983, and the first example entered service in 1985 with Atlantic Southeast Airlines, who operated on behalf of Delta Air Lines out of Atlanta. Despite an early string of accidents in the 1980s and 1990s, mostly related to icing and issues with the propeller manufacturer, the type was immediately popular, much more so than the Shorts SD3-60 it competed against which airlines would mostly retire by the early 1990s. Embraer further developed the type to include an extended range, combi, full cargo, and VIP military transport versions while the basic production EMB-120s were upgraded to the EMB-120RT standard post production, allowing for a higher takeoff weight. The type was most popular in the United States and Brazil, where over 100 of the type are still operated today. Production of the EMB-120 ended in 2001 as Embraer focused it's commercial aviation activities on it's jets, with the EMB-120 outlasting the rival Saab 340 in production by 2 years. Both Delta Air Lines and United Airlines kept a large number of the type active in their regional networks with SkyWest Airlines until 2015 when the type was retired and both airlines ended service to many small cities served for decades. Many of the EMB-120s, however, found new life as cargo aircraft where they are very active today around the world, still in their basic Skywest/United colors.
