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 · November

Rough patch crossing the jet stream in December — drinks went everywhere on the row behind me. Probably 45 minutes of actual turbulence. Nothing dangerous but definitely uncomfortable.

Business traveler · December

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