The 6h 35m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · January

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

First-time flyer · August

Kids barely noticed the turbulence — just some mild bumps crossing the Rockies. Seatbelt sign was on and off a couple times. Nothing dramatic.
