Passenger Reports

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

Nervous flyer · March

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.

Frequent flyer · 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.
