Passenger Reports

The over the North Atlantic section was legitimately rough. I was holding on to the armrests. Lasted maybe 40 minutes. One of the flight attendants had to sit down. Not a fun 10h 50m flight but we landed fine.
Solo traveler · May
Flew this in November expecting smooth skies based on past experience, but it was noticeably bumpier than usual. About an hour of moderate chop. Seatbelt sign basically stayed on.
Regular traveler · November
Moderate turbulence over the Atlantic — the kind where you're glad you kept your seatbelt on. Lasted about 30-40 minutes, then smoothed out. I've had worse on transatlantic routes.
