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

Some light chop over the Pacific — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in September.

Regular traveler · September

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