About the PDX–DEN route

The Portland to Denver 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, Southwest, Frontier, Alaska on Boeing 737 · Airbus A319 aircraft, with flights typically cruising at 36,000 feet over a distance of 1,141 miles (991 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 over the mountains, seatbelt sign on for what felt like forever. The flight attendants were calm which helped. Got through it.

Nervous flyer · April

More turbulent than I expected. The crossing the Rockies section was pretty rough — overhead bins rattling, some gasps from other passengers. Died down before landing.

Leisure traveler · November

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