Passenger Reports

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

The 3h 15m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · April

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