Passenger Reports

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

Parent traveling with kids · May

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

First-time flyer · October

Some light chop crossing the warm front — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in January.
