Passenger Reports

The somewhere over the ocean 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 5h 30m flight but we landed fine.

Solo traveler · March

Moderate turbulence crossing the dateline — 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

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