Aspen-Pitkin County Airport (Sardy Field) (KASE/ASE)

Aspen-Pitkin County Airport (KASE) sits in Aspen, Colorado, in the upper Roaring Fork Valley. The single 8,006 ft runway is typically long enough for most heavy and super-midsize jets. Heavy iron (G650, GLEX, F8X) is restricted by aircraft type rules due to surrounding mountain terrain + steep approach corridors. Field elevation 7,820 ft, with significant year-round density-altitude considerations + structural daytime VFR-favorable mountain operations (afternoon convective windows). KASE is one of the most demanding US mountain airports + the structural Aspen / Snowmass luxury ski / summer gateway. Heavy December-March + Food & Wine Classic (June) charter peaks. Ground time to downtown Aspen is 5 minutes; Snowmass Village is 20.
