Passenger Reports

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

Frequent flyer · January

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

First-time flyer · February

The 9h 10m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.
