Passenger Reports

The 18h 10m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · June

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.

First-time flyer · June

Kids barely noticed the turbulence — just some mild bumps over the plains. Seatbelt sign was on and off a couple times. Nothing dramatic.
