Passenger Reports

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

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

Parent traveling with kids · June

A few bumpy patches over the mountains, lasted maybe half an hour total. Drink service was paused briefly. Not unusual for this time of year.
