Passenger Reports

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

Regular traveler · April

There was some noticeable movement over the Pacific that made me grip the armrest. My seatmate (clearly a regular) didn't even look up from their book. Perspective.

First-time flyer · April

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