Passenger Reports

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.

Leisure traveler · January

Flew this in September 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 · September

The over the mountains section was legitimately rough. I was holding on to the armrests. Lasted maybe 40 minutes. One of the flight attendants had to sit down. Not a fun 12h 0min flight but we landed fine.
