Passenger Reports

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 · April

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

Regular traveler · October

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.
