Some light chop over the Front Range — 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 mountains that made me grip the armrest. My seatmate (clearly a regular) didn't even look up from their book. Perspective.

First-time flyer · February

The 1h 25m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.
