Passenger Reports

The over the North Pacific 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 16h 50m flight but we landed fine.

Solo traveler · April

Rough patch over the North Pacific in December — drinks went everywhere on the row behind me. Probably 45 minutes of actual turbulence. Nothing dangerous but definitely uncomfortable.

Business traveler · December

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