Passenger Reports

Rough patch mid-Pacific in January — drinks went everywhere on the row behind me. Probably 45 minutes of actual turbulence. Nothing dangerous but definitely uncomfortable.

Business traveler · January

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

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