Passenger Reports

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

First-time flyer · June

The 9h 15m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · January

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