Passenger Reports

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

Nervous flyer · May

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

Leisure traveler · February

The somewhere over Greenland 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 8h 25m flight but we landed fine.
