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

Parent traveling with kids · March

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

First-time flyer · May

The 17h 35m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.
