Passenger Reports

Some light chop over Central Asia — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in April.

Regular traveler · April

Kids barely noticed the turbulence — just some mild bumps crossing the Himalayas. Seatbelt sign was on and off a couple times. Nothing dramatic.

Parent traveling with kids · November

There was some noticeable movement crossing the Himalayas that made me grip the armrest. My seatmate (clearly a regular) didn't even look up from their book. Perspective.
