About the BOI–SAT route

The Boise to San Antonio 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 Southwest Airlines, Spirit Airlines on Boeing 737 · Airbus A321 · Boeing 757 aircraft, with flights typically cruising at 35,000 feet over a distance of 1,376 miles (1,196 nautical miles).

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

Passenger Reports

Moderate turbulence over the mountains — 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.
Frequent flyer · May
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 · April
Rough patch crossing the Rockies in February — drinks went everywhere on the row behind me. Probably 45 minutes of actual turbulence. Nothing dangerous but definitely uncomfortable.
