Passenger Reports

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

Business traveler · June

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

Nervous flyer · December

Flew this in April 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.
