Spokane International Airport (IATA:GEG,ICAO:KGEG,FAALID:GEG) is a commercial airport inSpokane, Washington, United States, located approximately 7 miles (11 km) west-southwest ofDowntown Spokane. It is the primary airport serving theInland Northwest, which consists of 30 counties and includes areas such as Spokane, theTri-Cities, both inEastern Washington, andCoeur d'Alene inNorthIdaho. The airport's code, GEG, is derived from its former name, Geiger Field, which honored MajorHarold Geiger (1884–1927).
As of 2023, Spokane International Airport (GEG) ranks as the 73rd-busiest airport in the United States in terms of passenger enplanements.[3] At 4,264,875 total passengers served in 2024, it is the second busiest airport in Washington. GEG is served by seven airlines withnon-stop service to more than 20 destinations in the continental US.[4]
It is included in theFederal Aviation Administration (FAA)National Plan of Integrated Airport Systems for 2017–2021, in which it iscategorized as a small-hub primary commercial service facility.[5]
Excluding military airfields, general aviation, and cargo airports, GEG Airport, at 6,140 acres (9.6 sq mi; 24.8 km2), is the largest commercial/public airport in all of Washington state in terms of land area.[1][6]


Known asSunset Field before 1941, it was purchased from the county by theWar Department and renamedGeiger Field (hence theIATA codeGEG) after MajorHarold Geiger, anArmy aviation pioneer who died in a crash in 1927.
DuringWorld War II, Geiger Field was a major training base bySecond Air Force as a group training airfield forB-17 Flying Fortress heavy bombardment units, with new aircraft being obtained fromBoeing nearSeattle. It was also used by Air Technical Service Command as an aircraft maintenance and supply depot; Deer Park Airport andFelts Field were auxiliaries.
In 1943, General Hap Arnold established the first formal fire protection training course at Geiger Field, Washington. It was used until 1946.
Geiger Field was served by a rail connection to theGreat Northern Railway.[7]
Geiger was closed in late 1945 and turned over toWar Assets Administration (WAA), then transferred to Spokane County and developed into a commercial airport. The airport hosted USAFAir Defense Commandinterceptor units during theCold War for air defense ofHanford Nuclear Reservation andGrand Coulee Dam. Built in 1942 as the Spokane Air Depot,Fairchild Air Force Base is four miles (6 km) to the west.
It became Spokane's municipal airport in 1946, replacingFelts Field, and received its present name in 1960, after the City of Spokane was allotted Spokane Geiger Field by the Surplus Property Act andAir Canada started service toCalgary.[8] In November 1972, the4702d Defense Wing moved to the airfield. It was still used by the Air Force into the early 1960s, with the84th Fighter Group operatingConvair F-106 Delta Dartinterceptors.[9][10] The airport code is still GEG, for Geiger Field.
The current Concourse A and B complex opened in 1965, designed by Warren C. Heylman and William Trogdon.[11][12]
A second level was added to Concourse A and Concourse B in 1974.[13]
The airport has a Master Plan,[14] which includes a third runway and gates added to Concourse C.
A newcontrol tower has been built south of the airport, replacing the one near Concourse C. The new control tower is the tallest one in the State. TheTerminal,Rotunda, and Concourse C Enhancement Project (TRACE) was recently completed, designed by Bernardo/Wills Architects, P.C.[15] The project, which concluded in November 2006, added retail space and expanded security checkpoints in the airport's three concourses, and gave the Rotunda an aesthetic renovation. In 2010, 2000 feet was added to Runway 3–21 and parallel taxiways 'A' and 'G', enabling heavier aircraft departures in summer months.
By 2023, the airport plans to add new gates, centralized security and expanded baggage claim space as it looks to add more direct flights, including to the east coast, to capitalize on and accommodate growing passenger and cargo traffic; the Spokane market has been hosting big events and attracting business to the area.[16][17]
On October 20, 2022, the airport broke ground on the first phase of the project which includes expansion of Concourse C. The $150 million addition will add 144,000 square feet, 6 new gates and modernization of the existing terminal.[18] The first portion of the expanded concourse, which includes three gates at the west end, opened in June 2024. The remainder of the project is planned to begin construction in late 2024 and be completed the following year.[19][20]
The second phase of the TREX program is focused on creating a centralized TSA screening checkpoint and baggage claim, as well as an improved operations center. This central connection will also allow easier navigation between the A/B and C concourses.[18] As of January 2023, the 145,000 square foot Central Hall is estimated to cost $179 million and has a planned construction timeline of 2025 to 2027.[21] Other projects planned in the TREX program include relocation of the rental car facilities, and renovation of the A/B concourse.[18]
The airport received $6.5 million from the2021 Bipartisan Infrastructure Law to help fund the project.[22]
The airport covers 6,140 acres (2,480 ha) and operates two paved runways:[1][23]
It is believed that the tower is the only federally-run air traffic control tower named for any single person. That honor was bestowed in 2010 on Ray Daves, theWorld War IIradioman who survivedPearl Harbor andMidway and went on to serve as an air traffic controller in Spokane after the war until the 1970s.[24][25]

The passenger terminal facility at Spokane International Airport has three main structures; Concourse A and B in the center, Concourse C to the southwest, and the Ground Transportation Center to the north. The three structures are immediately adjacent and connected, however the two concourse structures are not linked with an airside connector on thesterile side; as such, connecting passengers need to transit between Concourse A-B and Concourse C through the landside, non-sterile circulation.

The 1965 Concourse A/B complex includes the two concourses linked by a central rotunda area with dining and shopping vendors. The 37,000 sq ft (3,400 m2) rotunda is supported entirely along its perimeter and features no obstructions.[26] Concourse A houses 5 gates (11-15), while Concourse B houses 8 gates (1–8).
The Concourse A-B complex originally opened on April 1, 1965, and was designed by Warren C. Heylman and William Trogdon.[27] The new terminal cost a reportedUS$4,600,000 (equivalent to $45,900,000 in 2024) and was dedicated on May 8, 1965,[28] in a ceremony attended by SenatorWarren Magnuson andCivil Aeronautics Board chairAlan Boyd.[26] Designed in the Neo-Expressionism style, the building's architecture prominently features exposed concrete as well as distinct sculpted and monolithic architectural shapes and forms.
As the airport has continued to incrementally expand, some of the original architectural intent of the Concourse A-B complex has been lost. While several expansions to the concourse extended the building's original architectural style, other additions have altered it. In 1974, a second floor was added to both Concourses A and B to allow for the implementation ofpassenger boarding bridge access to aircraft. The new floors, while sharing some material commonality with the original Heylman and Trogdon concourse, lacked the same curvy and sculpted neo-expressionistic forms. The later additions of the ground transportation facility and Concourse C to the ends of the concourse building further altered the architecture by replacing its distinct bookend elevations and entrances with corridors to the adjacent buildings. Interior renovations in the mid-2000s also replaced many of Concourse A-B complex's original sculpted forms and monolithic materials with more rectilinear forms and contemporary finish materials. Despite this, many of the original architectural elements remain integral to the space (such as the exposed concrete roof trusses and concrete columns), creating a juxtaposition between the newer elements and the original architecture.
Under the proposed Terminal Renovation and Expansion (TREX) program to accommodate projected growth, the separate baggage claim areas in Concourse A-B and Concourse C would be consolidated into a single baggage claim with five carousels, and A-B would receive a renovation. Ultimately, operations at A-B would wind down under long-term plans to construct a new terminal in 2030, at the earliest.[29]
Southwest Airlines is the current primary occupant operating in and out of Concourse A.Delta andUnited Airlines both operate in and out of Concourse B.American Airlines operated in and out of Concourse B before relocating to Concourse C in March 2016.

Concourse C houses 9 gates, both upper (30-32) and lower (21a, 21b, 22-26). The lower level gates house regional turboprop aircraft, while the upper-level gates house narrow-body aircraft. The current iteration of Concourse C opened in 2000 after a $20 million redevelopment and expansion project, designed by Bernardo-Wills Architects.[30] The project, which broke ground in 1998 added 80,000 square feet (7,400 m2) to the concourse including a new baggage claim and two-story passenger facility. The 11,000-square-foot (1,000 m2) concourse was remodeled into service and operations functions.[31] The new Concourse C has a more contemporary architectural style, contrasting the appearance of the Concourse A and B complex, by employing a large use of metal cladding and large curtain window walls on its exterior building envelope. However, it draws inspiration from its neo-expressionist neighbor by architecturally expressing a modular, repetitive, and exposed structural grid through its façade and interior lobby areas.
Alaska Airlines and its subsidiary carrierHorizon Air were the primary occupants operating in and out of Concourse C afterFrontier Airlines ceased operations to Spokane in January 2015.[32] However, that changed onceAmerican Airlines relocated to Concourse C in March 2016. Alaska and American operate in and out of the upper-level gates, while Horizon operates in and out of the lower level gates.
In October 2022, the airport broke ground on Phase 1 of the Terminal Renovation and Expansion (TREX) program which includes expansion of Concourse C. The concourse is currently under construction and expected to reopen in late 2025.[18][20]

Spokane Transit operates four stops at Spokane International Airport, with bus routes 60 and 63. The airport is also served by theWSDOT'sTravel Washington Gold Line,Northwestern Trailways, Wheatland Express, Queen City Shuttle, and Special Mobility Service.
Aconsolidated rental car facility is located adjacent to the Ground Transportation Center on the north end of the main terminal. The consolidated facility opened in November 2008, replacing several satellite operations, and is intended to meet passenger growth at the airport for 20 years after its opening.[49]
