Friedman Memorial Airport

Friedman Memorial Airport (KSUN) sits 12 miles south of Sun Valley and Ketchum in the Wood River valley, at 5,317 feet elevation. It is the principal commercial and business-aviation airport for the Sun Valley resort circuit and the only commercial-grade field within reasonable ground time of one of the original American ski-resort destinations. Commercial service is modest (Alaska, United, Delta seasonal), and the airport handles a substantial UHNW private aviation flow during winter ski season and summer fishing and cultural seasons (Sun Valley Writers' Conference in July, Allen & Company conference window). The single runway 13/31 is 7,550 feet, which handles most current business jets but is constrained by terrain on both ends — captains need specific mountain-airport approval and recent KSUN experience, and weight planning is genuine on heavy or ultra-long-range departures, especially in summer. Atlantic Aviation operates the FBO. The Allen & Company conference week in July is the structural peak event — during this window the airport handles one of the highest densities of UHNW private aircraft in the world. Mountain weather is the dominant operational factor: orographic turbulence, sudden ceiling drops in winter that can drive diversions to KBOI or KTWF, and the standard density-altitude effects in summer. Ground time to Sun Valley and Ketchum is 20–30 minutes.
