Louisville Muhammad Ali International Airport

Louisville Muhammad Ali International Airport (KSDF) — note: should be KSDF for Louisville; the principal commercial and business-aviation airport for Louisville, Kentucky sits 5 miles south of downtown. Commercial service is significant (Southwest, Delta, American, United, Allegiant are the major carriers) and the field hosts UPS Airlines' Worldport — the largest UPS package-sorting facility in the world — which dominates overnight activity. The three runways at KSDF (17R/35L 11,890 ft, 17L/35R 8,580 ft, 11/29 7,250 ft) handle every current business jet without restriction. Two FBOs (Atlantic and Signature) handle business movements. Field elevation is 501 feet, no density-altitude concerns. The dominant operational considerations are the overnight UPS Worldport cargo rush (which constrains some night-time GA movements), summer Southeast thunderstorms, and the standard Ohio Valley weather pattern. The structural event peaks are the Kentucky Derby weekend (first Saturday in May — KSDF handles one of the highest densities of US private-jet traffic of any single weekend of the year), Breeders' Cup when hosted at Churchill Downs, and the Kentucky Bourbon Trail leisure flow. Ground time to downtown Louisville is 10–15 minutes; Churchill Downs is 5; the Bourbon Trail starts 20–30 minutes south.
