Passenger Reports

Flew this in March 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 · March

Moderate turbulence somewhere over the ocean — 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

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