Passenger Reports

The 13h 05m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · April

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

First-time flyer · February

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