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

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

Nervous flyer · June

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