Sidney–Richland Municipal Airport (IATA: SDY, ICAO: KSDY, FAA LID: SDY) is a mile west of Sidney, in Richland County, Montana. The airport is served by one airline, subsidized by the federal government's Essential Air Service program at a cost of $3,777,579 (per year).
The Federal Aviation Administration says this airport had 2,031 passenger boardings (enplanements) in calendar year 2008, 2,766 in 2009, and 3,659 in 2010. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a general aviation airport based on enplanements in 2008 (the commercial service category requires at least 2,500 enplanements per year).
Scheduled air service temporarily ceased on March 8, 2008, when Big Sky Airlines ended operations in bankruptcy. Great Lakes Airlines was given USDOT approval to take over Essential Air Service (EAS) and flights began in 2009. Between 2011 and 2013, service was provided under EAS contract by Silver Airways (formerly Gulfstream International Airlines). Effective December 10, 2013 service between Sidney and Billings is provided five times per day by Cape Air in Cessna 402Cs.
The first airline flights were Frontier DC-3s in September 1954; a commuter airline replaced Frontier when it ended DC-3 flights in 1968-69, but Frontier returned with Twin Otters and stayed until 1980.
In 2009 the airport had 6,815 aircraft operations, average 18 per day: 59% general aviation, 26% airline, 15% air taxi, and <1% military. 32 aircraft were then based at the airport: 84% single-engine and 16% multi-engine.
