Passenger Reports

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

First-time flyer · April

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

Parent traveling with kids · May

The 17h 00m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.
