About the ASE–IAD route

The Aspen to Washington DC route crosses the Rocky Mountains — one of the most turbulent regions in North America. Mountain wave turbulence occurs when strong winds blow over mountain peaks, creating powerful invisible waves that extend to cruise altitude. The worst turbulence typically occurs in the first 30–60 minutes when the aircraft is climbing over the range.

The route is served by United, American Airlines, Delta on Airbus A320 · Boeing 737 aircraft, with flights typically cruising at 35,000 feet over a distance of 1,571 miles (1,365 nautical miles).

💡 Tip: Mountain wave turbulence hits early. If flying over Rockies, expect the first hour to be bumpy.
