Kids barely noticed the turbulence — just some mild bumps over the Pacific. Seatbelt sign was on and off a couple times. Nothing dramatic.
Parent traveling with kids · April
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 · August
A few bumpy patches over the Pacific, lasted maybe half an hour total. Drink service was paused briefly. Not unusual for this time of year.
