Passenger Reports

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

Frequent flyer · April

The 1h 00m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · February

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.
