Passenger Reports

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 crossing the dateline section was pretty rough — overhead bins rattling, some gasps from other passengers. Died down before landing.

Leisure traveler · October

Moderate turbulence over the North 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.
