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.

First-time flyer · April

The 5h 35m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · August

A few bumpy patches over the subcontinent, lasted maybe half an hour total. Drink service was paused briefly. Not unusual for this time of year.
