Boise Air Terminal/Gowen Field

Boise Airport (KBOI) sits 3 miles south of downtown Boise, Idaho. The field handles modest commercial service (Southwest, Alaska, Delta, American, United, JetBlue, Allegiant, Frontier) and a meaningful flow of business aviation, particularly the rapidly-growing Treasure Valley corporate community (Micron Technology HQ, Albertsons, J.R. Simplot), the year-round Mountain West leisure flow (Sun Valley is 2 hours northeast), and the Idaho state government flow.

The three runways at KBOI (10R/28L 10,000 ft, 10L/28R 9,763 ft, 1/19 4,000 ft) handle every current business jet without restriction. Two FBOs (Western Aircraft and Jackson Jet Center) handle business movements. Field elevation is 2,871 feet, with modest summer density-altitude considerations. The dominant operational considerations are winter weather (persistent cold, occasional ice events, but Boise sees less snow than Spokane or Bozeman), summer thunderstorms, and the surrounding mountainous terrain (especially the Boise Front Range north of the field). Ground time to downtown Boise is 5–10 minutes; the rapidly-growing Meridian corporate corridor west of Boise is 15–25; Sun Valley via US-20 / SH-75 is 2.5 hours.

Boise Airport is a joint civil-military airport in the western United States in Idaho, three miles (5 km) south of downtown Boise in Ada County. The airport is operated by the city of Boise Department of Aviation, overseen by an airport commission. Boise Airport is the busiest airport in the state with more than 5.2 million passengers serviced in 2025. Boise Airport services roughly ten times as many passengers as the next busiest airport at Idaho Falls. In 2020 it serviced more passenger flights than all other Idaho airports combined.
