Passenger Reports

Moderate turbulence mid-Pacific — the kind where you're glad you kept your seatbelt on. Lasted about 30-40 minutes, then smoothed out. I've had worse on transatlantic routes.

Frequent flyer · April

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.

Regular traveler · July

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.
