Passenger Reports

This was genuinely difficult for me. Real bumps for a long stretch over the North Pacific, seatbelt sign on for what felt like forever. The flight attendants were calm which helped. Got through it.

Nervous flyer · March

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 · November

Flew this in January 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.
