Passenger Reports

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

Leisure traveler · April

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.

Regular traveler · January

The on the climb out 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 2h 27m flight but we landed fine.
