Passenger Reports

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.

First-time flyer · April

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 March.

Regular traveler · March

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