Passenger Reports

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

Frequent flyer · November

The 11h 30m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · August

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