Passenger Reports

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

First-time flyer · March

The 1h 45m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · October

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