Direct Flights to Sun Valley, Idaho (SUN)

New Service to Aspen, Colorado (ASE)

- Operation: The flight will operate daily using the same CRJ-700 aircraft type.
This addition connects Aspen with more U.S. destinations than any other airline, including Delta and United.
With these new domestic and international flight additions, American Airlines passengers have an exciting array of choices for their winter travel plans, whether they’re hitting the snowy slopes or relaxing on a sunny beach.
Tropical Getaways: Mexico Takes Center Stage
History-making routes to Mexico highlight American’s international expansion. Starting December 3, 2025, travelers can fly to Puerto Escondido, Mexico—marking the airline’s first-ever service to this hidden beach paradise. Just before that, on November 8, 2025, American will launch its inaugural international flight from Oklahoma City (OKC) to Cancun, opening new possibilities for Midwest travelers seeking winter sun.
Mountain Escapes: Idaho and Colorado Join the Network
For snow enthusiasts, American Airlines is introducing daily service to Sun Valley, Idaho (SUN) from both Chicago (ORD) and Phoenix (PHX) beginning December 18, 2025. Marketed as their “Wine and Alpine” offering, these routes provide one-stop connections from over 150 destinations nationwide to one of America’s most beloved winter sports locations.
The Sun Valley service will operate through April 6, 2026, on dual-class CRJ700 aircraft featuring both premium and economy options. Tourism data from Visit Sun Valley shows why this destination made the cut—with projected lodging occupancy increases of 7% in January, 8% in February, and an impressive 19% in March 2025.
Sun Valley offers something for everyone—from expert runs on Bald Mountain to family-friendly slopes on Dollar Mountain, plus attractions like the Nordic & Snowshoe Center, Trail Creek Cabin, and relaxing pools and spas.
Not to be outdone, Aspen, Colorado joins American’s expanded winter portfolio with a new daily nonstop flight from Charlotte (CLT) starting December 19, 2025. This addition solidifies American’s position as the carrier connecting Aspen to more U.S. cities than any competitor.
