Sundown Jet S.A. | Aviación Ejecutiva

Sundown Jet S.A. is an Argentine business aviation company based at San Fernando International Airport in the northern suburbs of Buenos Aires. Note that the listing on file places it in Chaco province; the company's own site and aviation press place it at San Fernando, Buenos Aires. The company says it has more than 20 years of experience in executive aviation.

It flies executive and medical charters and also offers aircraft management, fractional ownership and advice on buying and selling aircraft. Its client base covers private, corporate and medical travel in Argentina and across Latin America.

Sundown Jet operates its own aircraft. Industry publication ch-aviation reported in January 2026 that the fleet had seven aircraft: Learjet 45 and 45XR jets, a newly added Learjet 40XR, a US-registered Gulfstream G550 flown since mid-2025, King Air B200 and B350 turboprops, and a Cessna 208B Grand Caravan. The company's website lists the same aircraft types. That range runs from short regional hops in a Caravan or King Air to long-range international trips in the G550.

The company's chief executive, according to ch-aviation, is Federico Giménez. Aviation outlet Aviacionline reported that the company joined the Spanish luxury association Luxury Spain. Argentine business press has also described it as ARGUS-certified, though that claim was not confirmed with ARGUS.
