Passenger Reports

Moderate turbulence over the North Pacific — 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.

Frequent flyer · May

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.

Nervous flyer · February

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