What to Expect

Your flight from Bentonville to Spokane, heading northwest for about 3 hours and 20 minutes, crosses a variety of terrains, each with its own potential for bumps. Initially, you'll be over the Ozark Plateau, where convective turbulence, caused by rising warm air, can occur, especially in warmer months. Then you'll enter Tornado Alley, where severe convective turbulence is possible; pilots are very skilled at navigating these well-forecasted systems. As you move onto the Great Plains, you might experience clear-air turbulence (CAT), caused by shifting air currents at high altitudes, but pilots use tools to anticipate and avoid this. Finally, approaching Spokane, you'll cross the Northern Rockies, where mountain wave turbulence can occur as air flows over the peaks. Keep in mind these are common atmospheric conditions that pilots train extensively to manage; it's all part of a normal flight.

The Bentonville to Spokane route crosses the Northern Rockies, a rugged expanse of high peaks in Montana, Idaho, and Wyoming. Mountain wave turbulence is frequent here, especially when Pacific storm systems push strong winds over the Continental Divide. Pilots often report moderate chop between 30,000 and 40,000 feet over this region.

Turbulence Factors on This Route

• Convective Turbulence: The Ozark Plateau frequently lies at the convergence of contrasting air masses, fueling thunderstorms and convective turbulence.
• Clear-Air Turbulence (CAT): The jet stream frequently meanders over the Great Plains, producing wind shear and clear-air turbulence at cruising altitudes.
• Mountain Wave Turbulence: The Northern Rockies generate powerful lee waves when Pacific fronts drive westerly flow across the high terrain.

When Is This Route Bumpiest?

For the smoothest possible ride, fall and summer are generally your best bets on this route, followed by winter. In the fall, the atmosphere tends to be more stable, reducing convective activity over the Ozarks and Tornado Alley. Summer is also relatively calm. Spring, early summer, late fall, and early spring can be bumpier, especially when passing through Tornado Alley. This is because of increased convective activity, which leads to more thunderstorms and, therefore, more turbulence. Mountain wave turbulence over the Rockies is more common in winter and early spring due to stronger upper-level winds.

Tips for This Flight

If you're anxious about turbulence, booking a morning flight often means a smoother ride, as the atmosphere is usually more settled early in the day. Any turbulence you do encounter on this route will likely feel like driving on a road with potholes, or perhaps a sudden dip. To make yourself more comfortable, choose a seat over the wing, where motion is minimized, and stay well-hydrated, as this can help with any feelings of unease. Remember, the flight crew is there to ensure your safety and comfort, and they are highly experienced in handling all conditions. You've got this, and you'll be in Spokane before you know it.
