The 11h 35m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.
Leisure traveler · April
Some light chop crossing the Andes — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in November.
Regular traveler · November
There was some noticeable movement on the Andes crossing that made me grip the armrest. My seatmate (clearly a regular) didn't even look up from their book. Perspective.
