About the ASE–SFO route

The Aspen to San Francisco 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 33,000 feet over a distance of 846 miles (735 nautical miles).

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

Passenger Reports

Flew this in May expecting smooth skies based on past experience, but it was noticeably bumpier than usual. About an hour of moderate chop. Seatbelt sign basically stayed on.

Regular traveler · May

Rough patch over the mountains in September — drinks went everywhere on the row behind me. Probably 45 minutes of actual turbulence. Nothing dangerous but definitely uncomfortable.

Business traveler · September

This was genuinely difficult for me. Real bumps for a long stretch over the mountains, seatbelt sign on for what felt like forever. The flight attendants were calm which helped. Got through it.
