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.

Boise Airport currently has one terminal with two concourses and serves eight airlines. The terminal is a three-story building with four baggage carousels, rental car counters on the ground floor, all ticketing counters, a consolidated security checkpoint including TSA PreCheck and CLEAR Security, offices, and fast-food outlets.
The two concourses have 24 gates and 13 jet bridges. Concourse B has 13 gates and 11 jet bridges (with one jet bridge serving each of B21 a/b and B22 a/b). Airline gate assignments are broken down as follows: B10, B11, B21 a/b (United), B15, B17 (Southwest), B14, B16, B19 (Common Use), B18 (American), B20, B22 a/b (Delta). The common-use gates are used as follows: B14 (Delta), B16 (American, Frontier), B19 (Allegiant, Southwest, Sun Country). Concourse C serves Alaska Airlines and has 11 gates; however, only gates C8a and C12 are equipped with jet bridges, with the rest having covered walkways.
In 2016, Boise Airport released a new master plan outlining their short, medium, and long-term plans. Each of these terms would mark different stages of the airport's growth and renewal, with the largest projects being three new parking garages, upgrades to Concourse B, and a new Concourse A.
The new Concourse A will sit on the other side of the main terminal from concourses B and C in an existing rental car parking lot. It is scheduled to have ten new gates, all equipped with jet bridges and able to handle narrow-body aircraft. Plans call for one of the new gates to be equipped to handle wide bodied aircraft, five equipped for narrowbody aircraft, and four equipped for regional jets up to an A220. Phase 1 of the new concourse is scheduled to begin construction in 2027 and will include six gates, three for mainline aircraft and three for regional aircraft. The makeup of Phases 2 and 3 would depend on the needs of the airport and have not been determined yet.
Increasing passenger traffic at BOI requires the addition of parking. To this end, the airport is building three new parking garages. One will be a public garage for passengers with 940 spaces. This will be built on an existing surface lot. The other two garages, an employee garage and a rental car center garage, are being relocated to make room for Concourse A. The new employee garage will have 680 spaces and the rental car garage will have 880 spaces.
The airport has begun construction on its first two of the three parking garages. In late January 2022, it broke ground on the construction for the new employee parking garage after several delays, and its new public parking garage expansion. Both these projects plan to be finished by the end of 2023. The airport also plans to break ground on a new 2 part rental car garage in 2024, this will make room for the new Concourse A.
The new seven story consolidated rent a car garage (CONRAC) opened on September 1, 2026 with 10 different brands on 6 of the 7 floors. The facility includes Avis, Budget (Level 5/6) Payless (Level 6), Hertz, Dollar, Thrifty (Level 4), Sixt (Level 3), Enterprise, Alamo (Level 2), and National (Level 1).
