Passenger Reports

Moderate turbulence over Central Asia — the kind where you're glad you kept your seatbelt on. Lasted about 30-40 minutes, then smoothed out. I've had worse on transatlantic routes.

Frequent flyer · January

Rough patch over Central Asia 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 Central Asia section was pretty rough — overhead bins rattling, some gasps from other passengers. Died down before landing.
