Passenger Reports

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.
Frequent flyer · March
The 3h 30m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.
Leisure traveler · July
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.
