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.
On November 19, 2003, a $2.2 million air traffic control tower opened, giving controllers increased visibility. The new 115-foot-tall tower, which replaced the 43-foot tower, can accommodate four controllers.
In 2006, an Instrument Landing System (ILS) was commissioned and in 2007, a BI-6 radar system was added. These improvements allow aircraft to land in lower visibility conditions and increase the rate at which EGE can accept arriving aircraft in low visibility.
The airport completed a $40 million runway extension and rehabilitation project in 2009 which increased the length of the runway to 9,000. The extra runway length allows aircraft to take off at a heavier weight thereby increasing their range.
In 2012, a security checkpoint expansion project was completed which increased the number of passenger screening lanes from 2 to 4, and Alpenglo Express opened giving passengers a pre-security option for food and retail.
The airport continues to make improvements to the travel experience by adding cell-phone charging stations, improving the public address system, and adding water bottle fill stations.
The airport is served by four major airlines: American, Delta, United, and Air Canada with non-stop winter service to 11 major cities: Atlanta, Chicago, Dallas, Denver, Houston, Los Angeles, Miami, Minneapolis, New York (JFK), Newark, and Toronto. Summer service includes non-stop flights to Denver, Dallas, and Houston.
Comparing peak day passenger traffic makes Eagle County Regional Airport the second busiest airport in Colorado. In 2013, 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 $635,900,000. In addition, the Eagle County Regional Airport created 6,294 jobs, paying $217,500,000 in wages.
