Regular traveler · June

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 · April

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