Passenger Reports

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

Parent traveling with kids · January

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

First-time flyer · February

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