Passenger Reports

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

Business traveler · June

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

Leisure traveler · March

The crossing the jet stream 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 6h 55m flight but we landed fine.
