Passenger Reports

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.

Flew Newark–Grand Cayman in May, had some light turbulence in the middle portion of the flight. Brief and nothing concerning. This route is usually fine.

Business traveler · May

Kids barely noticed the turbulence — just some mild bumps over the islands. Seatbelt sign was on and off a couple times. Nothing dramatic.
