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

Some light chop crossing the Himalayas — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in September.
Regular traveler · September
The 1h 25m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.
