About the BZN–SEA route

The Bozeman to Seattle 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 541 miles (470 nautical miles).

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