Passenger Reports

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

Nervous flyer · June

Flew this in August 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 · August

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 9h 35m flight but we landed fine.
