Passenger Reports

Some light chop over the North Pacific — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in April.

Regular traveler · April

The 12h 15m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · January

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.
