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

Some light chop near the coast — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in October.

Regular traveler · October

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