Passenger Reports

Some light chop crossing the Rockies — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in January.
Regular traveler · January
A few bumpy patches crossing the Rockies, lasted maybe half an hour total. Drink service was paused briefly. Not unusual for this time of year.
Frequent flyer · August
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.
