Passenger Reports

The 19h 40m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · April

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.

First-time flyer · March

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