Grand Junction

Denver Air Connection was established by Key Lime Air to manage passenger flights, in operation since 1997. Denver Air Connection’s first flights were from Denver’s Centennial and Rocky Mountain Metro Airport to Grand Junction and conducted as public charters.


In 2010, the first 30-seat Embraer EMB-120 Brasilia turbo-prop was acquired enabling the expansion of charter capabilities to 30 NCAA/Collegiate charters for men’s and women’s sports teams. Then we began charters for oil field personnel, music groups and the movie industry. Our first flight attendants became part of the inflight crew with the acquisition of the Embraer. In 2011, the 30-seat Dornier 328 passenger jets were brought into the fleet.

Scheduled Passenger Service

In 2012, Denver Air Connection received approval to operate as a Part 121 air carrier with regular scheduled domestic passenger service to and from Grand Junction, CO with its Metroliner 23s.


In 2015, Denver Air Connection partnered with Sheridan and the State of Wyoming to provide daily passenger service to and from Denver International Airport and in 2016 service was expanded to include Riverton, Wyoming.

FAA Approval

In 2018, Denver Air Connection was the first Part 121 operator in the region to receive FAA approval for its Safety Management System (SMS).

Dornier 328 Jet

In 2018, the first Dornier 328Jet was added to the Part 121 passenger operations.

Sheridan & Riverton

The proving tests with the FAA were successfully completed in July 2018 in time to begin scheduled Part 121 jet service on its Sheridan and Riverton routes at the beginning of July 2018.


In May, 2019 flights to Telluride commenced. This was the first ever scheduled passenger jet service to the community and was made possible by the high-altitude performance capabilities of the Dornier 328 jet. This service enabled Denver Air Connection to secure an Interline Agreement with United Airlines.


Our Interline Agreement with United Airlines, the adoption of the Videcom airline reservation and ticketing system and Global Distribution Systems enables our passengers to search, book and reserve the lowest fares to more than 193 countries served by United Airlines.
