The 13h 45m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · April

There was some noticeable movement over the North 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

Flew Philadelphia–Seoul in January, had some light turbulence in the middle portion of the flight. Brief and nothing concerning. This route is usually fine.
