Passenger Reports

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

Frequent flyer · 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 · August

Was nervous about this flight but honestly didn't need to be. Smooth the whole way, the 5h 05m went by fast.
