Passenger Reports

The crossing the dateline 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 18h 05m flight but we landed fine.

Solo traveler · April

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

Business traveler · February

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