Flew San Juan–Houston in March, had some light turbulence in the middle portion of the flight. Brief and nothing concerning. This route is usually fine.

Business traveler · March

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.
