Passenger Reports

Totally smooth January flight. The seatbelt sign came on once briefly on descent but nothing actually happened. Great trip.

Leisure traveler · January

I always expect the worst on longer flights but this one surprised me. Very little turbulence, only a few small bumps on descent. Manageable even for me.

Nervous flyer · February

Did Seattle to Istanbul last January and it was genuinely one of the smoothest long-haul flights I've had. Barely any movement the whole way.
