Steamboat Springs Airport (Bob Adams Field) is a city-owned airport three miles northwest of Steamboat Springs, in Routt County, Colorado. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a general aviation facility. Larger commercial jet aircraft operated by scheduled passenger airlines currently operate into the Yampa Valley Airport (HDN) west of Steamboat Springs near Hayden, Colorado which can handle Boeing 737 and 757 jetliners as well as Airbus A319 and A320 jets, and has mainline jet flights during the winter ski season as well as year-round United Express regional jet service to Denver. Historical airline service According to the Official Airline Guide (OAG), Steamboat Springs Airport previously had scheduled passenger flights to Denver (DEN) operated by Rocky Mountain Airways with small de Havilland Canada DHC-6 Twin Otter aircraft during the mid 1970s followed by larger 50-passenger de Havilland Canada DHC-7 Dash 7s by the late 1970s. The twin engine Twin Otter turboprop as well as the four engine Dash 7 turboprop both feature short takeoff and landing (STOL) performance which was required due to Steamboat Springs' relatively short runway and high elevation. Rocky Mountain Airways later operated Dash 7 service into the airport on behalf of Continental Airlines via a code sharing agreement during the early and mid-1990s with up to ten flights a day to Denver. In 1997, Maverick Airways was operating Dash 7 service to Denver on behalf of the current version of Frontier Airlines via a code sharing agreement from January 1997 until their bankruptcy in May 1997. Since Maverick Airways shut down, the airfield has remained a general aviation airfield with no scheduled passenger airline service at the present time. Facilities The airport covers 436 acres (176 ha) at an elevation of 6,882 feet (2,098 m). Its one runway, 14/32, is 4,452 by 100 feet (1,357 x 30 m) asphalt. In 2008 the airport had 11,522 aircraft operations, average 31 per day: 95% general aviation and 5% air taxi. 82 aircraft were then based at this airport: 82% single-engine, 9% multi-engine, 2% jet, 6% helicopter, and 1% glider. There is a small terminal for private aviation and several hangars on the property. There are about 30 spots for aircraft on the apron. The Civil Air Patrol has an office and aircraft at the airport.
