Passenger Reports

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

Frequent flyer · April

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 · October

Fly this route pretty regularly for work. Most of the time it's smooth — January was completely fine, not a bump worth mentioning.
