Passenger Reports

The crossing the Himalayas 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 6h 30m flight but we landed fine.

Solo traveler · June

Moderate turbulence crossing the Himalayas — 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 · August

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