Boise Airport (IATA: BOI, ICAO: KBOI, FAA LID: BOI) (Boise Air Terminal or Gowen Field) 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.
Boise is a landing rights airfield requiring international general aviation flights to receive permission from a Customs and Border Protection officer before landing.
In addition to being a commercial and general aviation airport, Boise also functions concurrently as a USAF military facility as used by the 124th Fighter Wing (124 FW) of the Idaho Air National Guard on the Gowen Field Air National Guard Base portion of the airport. The 124 FW operates the A-10 Thunderbolt II aircraft.
The National Interagency Fire Center is based in the city of Boise and the Boise Airport is used for logistical support. The United States Forest Service (USFS) also uses Boise Airport as a base for aerial firefighting air tankers during the wildfire season.
Boise Airport enplaned 2,248,435 passengers in 2022, an increase of 24% vs. 2021 when 1,806,838 passengers were enplaned.
