Passenger Reports

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

Leisure traveler · June

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 7h 15m flight but we landed fine.

Solo traveler · September

Moderate turbulence over the subcontinent — 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.
