Passenger Reports

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 05m flight but we landed fine.

Solo traveler · May

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 · March

Moderate turbulence over the Midwest — 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.
