Passenger Reports

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

Parent traveling with kids · January

The 6h 40m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · August

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