Passenger Reports

Did Haikou to Changsha 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

Was nervous about this flight but honestly didn't need to be. Smooth the whole way, the 1h 50m went by fast.

First-time passenger · May

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