Passenger Reports

More turbulent than I expected. The over the North Pacific section was pretty rough — overhead bins rattling, some gasps from other passengers. Died down before landing.

Leisure traveler · November

The somewhere over the ocean section was legitimately rough. I was holding on to the armrests. Lasted maybe 40 minutes. One of the flight attendants had to sit down. Not a fun 14h 0m flight but we landed fine.

Solo traveler · March

Flew this in July expecting smooth skies based on past experience, but it was noticeably bumpier than usual. About an hour of moderate chop. Seatbelt sign basically stayed on.
