Historical airline service

Frontier Airlines (1950-1986) continued to serve Farmington with DC-3s through the 1950s and added flights to Phoenix making several en-route stops as well. In 1958 Frontier created a mini-hub at Farmington operating 13 flights per day with as many as five DC-3 aircraft on the ground at one time. Through the 1960s Frontier upgraded their aircraft with Convair 340 piston engine aircraft and later with Convair 580 turboprops. By 1981, Frontier had discontinued all flights to Albuquerque, Phoenix, and Salt Lake City; however, the flights to its Denver hub (with a fuel stop in Durango) were upgraded to Boeing 737-200 jetliners from 1982 through 1984. The Denver flights were then reverted to Convair 580 aircraft operated as Frontier Commuter before all service was discontinued in early 1985.^[3]

Aspen Airways first came to Farmington for a period in 1979 and flew Convair 580s nonstop to Denver and Albuquerque. The carrier returned to Farmington in 1983 with flights only to Denver^[4] and became a United Express affiliate in 1986.^[5]

The airport received a Small Community Air Service Development Program grant in 2019 for SkyWest Airlines to begin service to Denver as United Express. The service was set to begin on October 15, 2020, but was delayed by the COVID-19 pandemic and later cancelled due to a shortage of pilots at SkyWest. However, once a day inbound and outbound flights between Farmington and Denver resumed in May 2025.^[6]
