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

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

Nervous flyer · October

More turbulent than I expected. The over the plains section was pretty rough — overhead bins rattling, some gasps from other passengers. Died down before landing.
