Passenger Reports

Flew this in April 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 · April

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

Business traveler · April

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