Passenger Reports

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

Leisure traveler · May

Moderate turbulence crossing the ridge — 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 · May

Flew this in February 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.
