Ski season is the reason for most of this traffic. Chicago families with homes or regular stays in Aspen and Snowmass fly out for holidays, spring break and long weekends from December to March, with a second, smaller wave in summer for the Aspen Ideas Festival, the Food & Wine Classic and hiking. Aspen-Pitkin County is a high-altitude mountain airport with operating restrictions, so not every aircraft can use it, and weather can close it. Eagle County Airport near Vail is the usual alternative, about a two-hour drive from Aspen.
