Passenger Reports
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.

The 18h 00m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.
