Passenger Reports

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

Leisure traveler · April

Flew this in November 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.

Regular traveler · November

The over the Pacific 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 19h 50m flight but we landed fine.
