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

Frequent flyer · January

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

First-time flyer · March

The 5h 25m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.
