About the SLC–STL route

The Salt Lake City to St. Louis 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 35,000 feet over a distance of 1,153 miles (1,002 nautical miles).

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

Passenger Reports

Some light chop on the climb out — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in May.

Regular traveler · May

There was some noticeable movement over the Front Range that made me grip the armrest. My seatmate (clearly a regular) didn't even look up from their book. Perspective.

First-time flyer · June

A few bumpy patches crossing the ridge, lasted maybe half an hour total. Drink service was paused briefly. Not unusual for this time of year.
