Abraham Lincoln Capital Airport is a civil-military airport in Sangamon County, Illinois, United States, three miles (6 km) northwest of downtown Springfield. It is owned by the Springfield Airport Authority (SAA).
The Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2023–2027 categorized it as a non-hub primary commercial service facility.[2]
It is the seventh busiest airport of the 12 commercial airports in Illinois.
The airport was dedicated in November 1947 under the name "Capital Airport." It came after pressure to construct a modern facility, as American Airlines and Chicago & Southern Airlines had canceled flights to Springfield in 1938 and 1939 respectively due to inadequate facilities at Capital Airport's predecessor. Construction on the new airport was begun soon after those cancellations but was delayed due to World War II.[3] [4]
The original airport had three 5300-foot runways, a service apron, a temporary passenger terminal, and T-hangars for 38 aircraft.
Two units of the Illinois National Guard were stationed at the airport in 1946, and one of them remains at the airport today.
In 2018, the airport embarked on an upgrade of its passenger terminal after receiving nearly $7 million from the Airport Improvement Program, a grant sponsored by the Federal Aviation Administration. The airport also worked to improve general aviation facilities like the FBO and hangars; roadways; and parking lots.[5] [6]
The coronavirus pandemic brought about airline suspensions at the airport, marking a significant downturn of traffic through the airport. Airlines returned service as travel picked up and after receiving money from the federal CARES Act to prop up flights.[7]
The Illinois Department of Transportation named SPI the top primary airport in the state in 2020. The department considered things such as how well the airport worked with the state's Division of Aeronautics, the airport's safety record, promotion of aviation and educational events and general maintenance.[8]
In 2021, the airport received $3 million in funding from the State of Illinois to upgrade facilities during the travel downturn caused by the Covid-19 pandemic. The funds went towards rehabilitating the north airport public parking lot and the north airport roadway. The airport also began constructing a new crosswind runway in 2021 to accommodate more traffic in a wider variety of wind conditions.[9] [10] In 2022, runway 18-36 was removed.
The airport is taking significant steps to prepare their facilities to accommodate electric-powered aircraft. The airport broke ground on a solar energy farm in 2022 to increase the role of renewable energy in powering the airport, with the goal of powering over 90% of the airport's needs with renewables.[11] [12]
The airport is home to Capital Airport Air National Guard Station, a 91acres facility on land leased from the Springfield Airport Authority (SAA). It is home to the 183d Fighter Wing (183 FW), an Illinois Air National Guard unit operationally gained by the Air Combat Command (ACC) and State Headquarters, Illinois Air National Guard. Historically a fighter unit, the 183 FW consists of 321 full-time and 800 part-time military personnel (total strength 1,321).
The airport covers 2300acres at an elevation of 598 feet (182 m). It has two runways: 4/22 is 8,001 by 150 feet (2,439 x 46 m) concrete; and 13/31 is 7,400 by 150 feet (2,256 x 46 m) asphalt.[13]
In the year ending July 31, 2022, the airport had 25,915 aircraft operations, average 71 per day: 64% general aviation, 20% military, 15% air taxi, and 2% commercial. For the same time period, 93 aircraft were based at the airport: 69 single-engine and 6 multi-engine airplanes, 12 jets, 4 helicopters, 1 glider, and 1 ultralight.
The airport has an FBO offering fuel, general maintenance, catering, hangars, courtesy cars, conference rooms, a crew lounge, snooze rooms, and more.
The airport terminal has a Subway, a gift shop, an automated teller machine, TV, and a lounge.
Sangamon Mass Transit District, the operator of public transit in Springfield, does not serve the airport as of 2023.
Allegiant Air and Breeze Airways use mainline jets to service the airport; American Eagle flights from Springfield use regional jets.
The airport was previously served by Ozark Airlines McDonnell Douglas DC-9-10s, DC-9-30s and Fairchild Hiller FH-227s to St. Louis and Chicago O'Hare Airport. Air Illinois flew BAC One-Elevens (to St. Louis and Chicago) and also served the airport with Hawker Siddeley HS 748s, Handley Page Jetstreams and de Havilland Canada DHC-6 Twin Otters. Air Illinois HS 748s flew nonstop among other routes to the now-closed Meigs Field on the lakefront next to downtown Chicago.
