Passenger Reports

The 8h 40m flight had some light shaking around the halfway point. Nothing spilled, nobody panicked. Just normal flying.

Leisure traveler · November

Some light chop over the North Atlantic — 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 mid-Atlantic that made me grip the armrest. My seatmate (clearly a regular) didn't even look up from their book. Perspective.
