Passenger Reports

The over the subcontinent 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 5h 30m flight but we landed fine.

Solo traveler · June

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

Leisure traveler · January

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.
