Passenger Reports

The 9h 15m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · 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 · May

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