Passenger Reports

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

Regular traveler · July

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

First-time flyer · November

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