Eagle County Regional Airport is located south of Interstate 70 just off Highway 6 between the towns of Eagle and Gypsum, Colorado.

The original runway was built in 1930s under the direction of the Civil Aeronautics Authority as an emergency landing strip for a Denver to Los Angeles air route.

The airport was dedicated on Sept. 14, 1947 and provided general aviation services for many years. In 1989, there were 277 commercial passengers.

In 1996, a $9 million, 36,000 sq. ft. passenger terminal was unveiled, accommodating a 73 percent increase in passengers during that season. The demands on the new terminal prompted an additional 30,000 sq. ft. expansion in 2001, to accommodate the growing popularity of commercial air service to EGE.

The airport is served by four major airlines: American, Continental, Delta, and United, with non-stop service to 13 hub airports in 12 major cities: Atlanta, Chicago, Cincinnati, Dallas, Denver, Detroit, Houston, Los Angeles, Miami, Minneapolis, New York (JFK and La Guardia), and Newark.

Since 1994 annual airport operations have increased 214 percent and since 1993 annual passenger enplanements have increased 47 fold. This growth has earned the Eagle County Regional Airport the ranking of third busiest airport in Colorado based on annual airline passenger traffic numbers. Comparing peak day passenger traffic makes Eagle County Regional Airport the second busiest airport in Colorado.

In 2008, a study commissioned by the Colorado Department of Transportation Aeronautics Division found that the total quantifiable impact on the local economy from the airport in that year totaled $982,170,400. In addition, the Eagle County Regional Airport created 10,467 jobs, paying $293,886,700 in wages.

On November 19, 2003, a $2.2 million air traffic control tower opened, giving controllers increased visibility. The new 115-foot-tall air traffic control tower, which replaced the 43-foot tower, allows for four controllers.

In 2006 an Instrument Landing System (ILS) was commissioned and in 2007 a BI-6 radar system was added which has increased the arrival acceptance rate at EGE. The effect of these navigational aids is twofold: allowing aircraft to land in lower visibility conditions and increasing the rate at which EGE can accept the arriving aircraft in low visibility conditions.

Other recent projects for the Eagle County Regional Airport include the completion of a 1,000 foot runway expansion and rehabilitation of the existing runway.
