Leisure traveler · May

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.

First-time flyer · October

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