Passenger Reports

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 · June

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

Nervous flyer · July

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 1h 05m flight but we landed fine.
