Passenger Reports

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

Business traveler · April

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

Leisure traveler · November

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