About the BOS–GEG route

The Boston to Spokane 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 Delta Air Lines, American Airlines, Alaska Airlines on Boeing 737 · Airbus A321 · Boeing 757 aircraft, with flights typically cruising at 37,000 feet over a distance of 2,267 miles (1,970 nautical miles).

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

Passenger Reports

This was genuinely difficult for me. Real bumps for a long stretch on the climb out, seatbelt sign on for what felt like forever. The flight attendants were calm which helped. Got through it.
Nervous flyer · June
Flew this in September 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 · September
Moderate turbulence crossing the Rockies — the kind where you're glad you kept your seatbelt on. Lasted about 30-40 minutes, then smoothed out. I've had worse on transatlantic routes.
