Passenger Reports

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.

Business traveler · April

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