  ## History
  
  ### Historic airline service
  
  The original Frontier Airlines (1950-1986) served the airport for many years. In 1950 Frontier Douglas DC-3s flew to Denver, Salt Lake City, Billings, Casper, Cheyenne and other cities. By 1964 Frontier had introduced Convair 580s nonstop to Denver, Casper, Jackson, WY, and Rock Springs and direct to Salt Lake City, Albuquerque, Billings, Cheyenne, Laramie and Cody. Frontier Airlines predecessor Challenger Airlines served Riverton in the 1940s.
  
  In 1979 Frontier Boeing 737-200s began serving the airport, along with Convair 580s. Frontier 737s flew direct to Denver via Casper; by 1985 Frontier had left the airport. Frontier was the only airline that flew mainline jets to the airport.
  
  Frontier's service was replaced by Pioneer Airlines Swearingen Metroliners nonstop to Denver, code sharing flights as Continental Express for Continental Airlines. By 1989 Continental Express nonstops to Denver were Rocky Mountain Airways ATR 42s and Beechcraft 1900Cs. In 1995 the Continental Express code share service at the airport was being operated by GP Express Airlines with Beechcraft 1900Cs nonstop to Denver. By 1991 United Express (Mesa Airlines) had joined Continental Express at the airport with Beechcraft 1900Cs nonstop to Denver flown via a code sharing agreement with United Airlines. Continental shut down its hub in Denver and by 1999 only United Express (Great Lakes Airlines) served the airport, with nonstop Beechcraft 1900s to Denver. Great Lakes later lost its United Express designation but continued to serve the airport as an independent airline before dropping Riverton.
  
  ### Recent developments
  
  Great Lakes Airlines previously served the airport with Beechcraft 1900Ds. On November 1, 2016 Great Lakes introduced larger Embraer EMB-120 Brasilias on most of its flights to Denver. However, Great Lakes soon went out of business, ending service to Riverton.
  
  SkyWest Airlines operating as United Express replaced Key Lime Air service to Denver on January 12, 2020 when they took over the subsidized air service contract for Riverton and Sheridan.
  
  In 2020, the name changed from Riverton Regional Airport to Central Wyoming Regional Airport.
