Passenger Reports

A few bumpy patches crossing the dateline, lasted maybe half an hour total. Drink service was paused briefly. Not unusual for this time of year.

Frequent flyer · April

There was some noticeable movement mid-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

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