Passenger Reports

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

Nervous flyer · June

The over the Atlantic 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 9h 40m flight but we landed fine.

Solo 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.
