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.
