Passenger Reports

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 · June

Flew this in July expecting smooth skies based on past experience, but it was noticeably bumpier than usual. About an hour of moderate chop. Seatbelt sign basically stayed on.

Regular traveler · July

Rough patch over the North Atlantic in April — drinks went everywhere on the row behind me. Probably 45 minutes of actual turbulence. Nothing dangerous but definitely uncomfortable.
