KLEX is the ICAO code for Blue Grass Airport (IATA LEX), located in Lexington, KY.
Blue Grass Airport (KLEX) sits 4 miles west of downtown Lexington, Kentucky, in the heart of Bluegrass horse country. The field handles modest commercial service (American, Delta, United, Allegiant) and a meaningful flow of business aviation, particularly driven by the Thoroughbred horse industry (Lexington is the global epicenter of horse breeding — Claiborne Farm, Three Chimneys, Coolmore America, and hundreds of others are within 30 minutes), the Toyota Motor Manufacturing Kentucky plant in Georgetown, and the year-round bourbon-trail tourism flow.
The two runways at KLEX (4/22 7,003 ft, 9/27 4,001 ft) handle most current business jets up through heavy operations on the longer 4/22. TAC Air operates the FBO. Field elevation is 979 feet, no density-altitude concerns. The dominant operational considerations are Kentucky weather (occasional winter ice events, summer thunderstorms, freezing rain), and the structural Keeneland horse-racing season (April spring meet and October fall meet — both drive concentrated UHNW private-jet traffic). The Breeders' Cup at Keeneland (when hosted) is a major event peak. Ground time to downtown Lexington is 5 minutes; Keeneland Race Course is 2; the major horse farms are 15–30; downtown Louisville via I-64 is 80 minutes.
Blue Grass Airport is a public airport in Fayette County, Kentucky, United States, 6 miles west of downtown Lexington. Located among horse farms and situated directly across from Keeneland Race Course, Blue Grass Airport is the primary airport serving central and eastern Kentucky. In 2025, LEX served 1,614,053 passengers, an all-time record for the facility, breaking the old record set in 2024. The 2025 passenger totals was 2.7 percent higher than in 2024. Four major airline carriers serve its passengers: Allegiant Air, American Airlines, Delta Air Lines, and United Airlines.
