Telluride Regional Airport is a public airport six miles west of Telluride, in San Miguel County, Colorado, United States. It is owned by the Telluride Regional Airport Authority. At an elevation of 9,078 feet above sea level, it was the highest commercial airport in North America with scheduled passenger flights when Great Lakes Airlines resumed scheduled passenger service in December 2016; however, those flights ceased in March 2018. In August 2018, commercial service returned with the introduction of Boutique Air, and the airport remains the highest airfield in the U.S. with scheduled passenger flights, and the second highest overall airfield in the US behind Leadville Airport. Denver Air Connection is currently the only airline flying scheduled passenger flights from Telluride with daily nonstop flights to Denver and Phoenix. Denver Air operates the Fairchild-Dornier 328JET into Telluride. The 328JET is one of the few regional jet airliners in service capable of operating at such high field elevations as TEX.
