Assistant Aviation Director Dan Gallagher will assume the role of interim director while the city conducts a national search for a new director. Gallagher has been with the Colorado Springs Airport since 2010.
Earle has agreed to serve as senior adviser of airport and aviation affairs for the remainder of the year to assist the city and the interim director in the transition.
Earle was not available for comment Friday.
In a prepared statement Earle said: “It’s been an honor to serve at Colorado Springs Airport over the past nine and a half years. I’ve had the privilege of working with one of the finest staffs in the airport industry and have enjoyed the support of a truly great community.”
The airport took a blow in recent months when Frontier Airlines ended its five-year presence here. The airline, which had cut its service from the Springs to Denver effective March 2, also will soon end its remaining nonstop flights, including those to Phoenix and Los Angeles, that it not so long ago touted with great fanfare.
Frontier flights represented about 19 percent of the airport’s traffic.
In recent years, Earle oversaw the airport’s $22.8 million terminal improvement program, aimed at helping the airport become more customer-friendly and make a statement about Colorado Springs and its offerings to the 2 million passengers coming and going each year through the airport.
The terminal project included installation of a fully automated baggage screening system, expansion of the security checkpoint, a new premium security line, two new restaurants and updated interior signs and video displays.
