Passenger Reports

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

Leisure traveler · April

Flew this in May 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 · May

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